Passage 1: The Global Spread of Coffee
Few crops have shaped global trade and social life as pervasively as coffee. Today it is cultivated across dozens of countries and consumed daily by hundreds of millions of people, but its journey from a wild shrub in the Ethiopian highlands to one of the most widely traded agricultural commodities on Earth took several centuries and passed through the hands of traders, colonial companies, and ordinary patrons of a new kind of public space.
By the 17th century, coffee had reached the Ottoman Empire and, soon after, Europe, where it gave rise to the coffeehouse — an institution that would prove almost as influential as the drink itself. Unlike taverns, which centered on alcohol and were often restricted along class lines, coffeehouses in cities such as London, Paris, and Vienna offered a rare social space where a merchant, a scholar, and a craftsman might sit at the same table, debate the news of the day, and exchange ideas for the price of a cup. Some historians argue that these spaces functioned as informal universities, incubating scientific societies, political movements, and even early financial institutions.
Although coffee cultivation began in Ethiopia, it was Yemeni traders who first controlled its export, guarding their monopoly so closely that exporting a living coffee plant was reportedly punishable by death. For roughly a century, virtually all coffee entering global trade passed through the Yemeni port of Mocha, giving the region enormous commercial leverage.
That monopoly did not last. European colonial trading companies, most notably the Dutch East India Company, eventually acquired live coffee plants and established plantations in territories with suitable climates — first in Java, then across the Caribbean and Latin America. This shift permanently ended the geographic monopoly that had defined the trade for over a century, and by the 18th century, coffee had become a genuinely global commodity rather than a regional one.
Questions 1–8
1. The word "pervasive" in paragraph 1 is closest in meaning to:
- (A) temporary
- (B) widespread
- (C) expensive
- (D) controversial
Show answer
Answer: (B) widespread
The passage describes coffee's influence as reaching "nearly every region and economic class," which is what "pervasive" signals — reread the sentence around an unfamiliar word before choosing.
2. According to paragraph 2, why did coffeehouses become important gathering places in 17th-century Europe?
- (A) They were the only buildings open past sunset.
- (B) They served food that was otherwise hard to find.
- (C) They allowed people of different social classes to mix and exchange ideas over a cheap drink.
- (D) They were funded directly by European governments.
Show answer
Answer: (C)
This is stated directly in the passage: coffeehouses offered "a rare social space where a merchant, a scholar, and a craftsman might sit at the same table." Watch for options like (A) and (D) that sound plausible but are never actually claimed in the text.
3. It can be inferred from paragraph 2 that before coffeehouses existed, opportunities for people of different social classes to interact were:
- (A) common
- (B) limited
- (C) illegal
- (D) unnecessary
Show answer
Answer: (B) limited
The passage calls the coffeehouse a "rare" social space for class mixing — if it was rare, the implication is that such mixing was not common before. Inference questions ask you to take one small logical step beyond a stated fact, not to guess freely.
4. Which of the following best expresses the essential information in this sentence from paragraph 3: "Although coffee cultivation began in Ethiopia, it was Yemeni traders who first controlled its export, guarding their monopoly so closely that exporting a living coffee plant was reportedly punishable by death."
- (A) Ethiopia and Yemen jointly controlled the coffee trade for centuries.
- (B) Yemeni traders dominated coffee exports from an Ethiopian crop and tried to prevent the plant itself from leaving their control.
- (C) Coffee cultivation was illegal everywhere except Ethiopia.
- (D) Yemeni traders invented coffee cultivation.
Show answer
Answer: (B)
(D) contradicts the sentence directly — Ethiopia is named as the origin. (A) invents a joint-control claim never made. (C) misreads a very specific export restriction as a general ban on cultivation.
5. The author mentions the Dutch East India Company in paragraph 4 in order to:
- (A) argue that Dutch colonization was primarily driven by coffee.
- (B) give an example of how coffee cultivation eventually spread beyond Yemeni control.
- (C) criticize European colonial trading practices.
- (D) explain why coffee prices fell in the 18th century.
Show answer
Answer: (B)
Rhetorical purpose questions ask why a detail is mentioned, not just what it says. The Dutch East India Company example directly follows the claim that Yemen's monopoly eventually broke — it functions as supporting evidence for that point.
6. According to the passage, all of the following are given as reasons for coffee's spread EXCEPT:
- (A) Coffeehouses functioned as social and intellectual hubs.
- (B) European trading companies established plantations outside Yemen.
- (C) Coffee was believed to have medicinal properties that cured most diseases.
- (D) Colonial powers found climates suitable for cultivation in their overseas territories.
Show answer
Answer: (C)
Negative factual questions ask you to find the one option NOT supported by the passage. (A), (B), and (D) are each stated; (C) overstates a much narrower claim (if any) — a common trap is inflating a modest claim in the passage into an extreme one in the answer choice.
7. Look at the four squares [■] that indicate where the following sentence could be added to paragraph 4: "This shift permanently ended the geographic monopoly that had defined the trade for over a century." Where would the sentence best fit?
- (A) Square 1
- (B) Square 2
- (C) Square 3
- (D) Square 4
Show answer
Answer: (Depends on placement — choose the square immediately after the sentence describing plantations being established outside Yemen)
Insertion questions are solved by matching a transition word or pronoun in the new sentence — here, "this shift" — to the idea it must refer back to. It has to follow the sentence that describes the actual shift (new plantations outside Yemeni control), not precede it.
8. Directions: An introductory sentence for a brief summary is provided: "Coffee spread from a regional Ethiopian crop to a global commodity through a combination of social, commercial, and colonial forces." Select the THREE answer choices that express the most important ideas in the passage.
- (A) Coffeehouses created new spaces for social and intellectual exchange across class lines.
- (B) Yemeni traders initially controlled coffee's export from its Ethiopian origins.
- (C) Coffee is grown today primarily in Central and South America.
- (D) European colonial trading companies eventually broke Yemen's export monopoly.
- (E) Instant coffee was invented in the early 20th century.
- (F) Coffee cultivation requires specific altitude and rainfall conditions.
Show answer
Answer: (A), (B), (D)
The three correct choices each map to one of the passage's three main movements: the social role of coffeehouses, the original Yemeni monopoly, and its eventual collapse under colonial trading companies. (C), (E), and (F) are either never discussed or are minor/unstated details.
Passage 2: Circadian Rhythms and Human Health
Nearly every living organism, from single-celled bacteria to human beings, possesses an internal biological clock that helps synchronize its behavior and physiology with the roughly 24-hour cycle of light and darkness. In humans, this circadian system influences far more than the sleep-wake cycle: it regulates body temperature, hormone release, digestion, and even the timing of cell repair processes.
At the center of this system lies a small cluster of neurons in the brain called the suprachiasmatic nucleus, or SCN, which acts as the body’s master clock. The SCN receives direct input from light-sensitive cells in the eye and coordinates timing signals dispatched to organs throughout the body, including the liver, heart, and digestive system, each of which maintains its own local circadian rhythm that must stay roughly in step with the master clock. Light is the strongest of these signals, which is why sudden time-zone changes are so disruptive.
When behavior and the internal clock fall out of step — a state researchers call circadian misalignment — consequences can follow. Shift work, in which employees regularly rotate between day and night schedules, is one of the most commonly studied causes of this mismatch. Chronic circadian misalignment has been associated not only with fatigue and impaired concentration, but with longer-term risks including metabolic disorders and cardiovascular disease, though researchers caution that correlation alone cannot establish that misalignment directly causes these conditions.
Much of what is known about circadian misalignment in real-world settings comes from studies of night-shift nurses, whose irregular schedules make them a frequently studied population in occupational health research. Findings from these studies have informed broader recommendations about schedule design, light exposure, and meal timing for anyone whose work or lifestyle regularly conflicts with a typical day-night cycle.
Questions 9–16
9. The word "synchronize" in paragraph 1 is closest in meaning to:
- (A) disrupt
- (B) align
- (C) measure
- (D) accelerate
Show answer
Answer: (B) align
The passage describes the circadian clock working to keep bodily processes "synchronize[d] with the roughly 24-hour cycle of light and darkness" — that is, aligned with it.
10. According to paragraph 2, what role does the suprachiasmatic nucleus play in the body?
- (A) It directly controls muscle movement.
- (B) It acts as the body's master clock, coordinating timing signals sent to other organs.
- (C) It stores long-term memories related to daily routines.
- (D) It regulates body temperature independently of light exposure.
Show answer
Answer: (B)
This is a factual information question answered directly from the text, which names the suprachiasmatic nucleus as the structure that "coordinates timing signals dispatched to organs throughout the body."
11. It can be inferred from paragraph 3 that shift workers who frequently change between day and night schedules are likely to:
- (A) develop stronger circadian rhythms than people with fixed schedules.
- (B) experience a mismatch between their internal clock and their actual sleep-wake schedule.
- (C) require less sleep overall than the general population.
- (D) be unaffected by circadian rhythm disruption.
Show answer
Answer: (B)
The passage explains that circadian misalignment occurs when behavior and the internal clock fall out of step, and specifically cites shift work as a common cause — the inference follows in one direct step from that stated cause-and-effect relationship.
12. Which of the following best expresses the essential information in this sentence from paragraph 3: "Chronic circadian misalignment has been associated not only with fatigue and impaired concentration, but with longer-term risks including metabolic disorders and cardiovascular disease, though researchers caution that correlation alone cannot establish that misalignment directly causes these conditions."
- (A) Circadian misalignment has been proven to cause metabolic and heart disease.
- (B) Circadian misalignment is linked to several short- and long-term health issues, but a direct causal link isn't yet established.
- (C) Only fatigue and concentration problems are connected to circadian misalignment.
- (D) Researchers have disproven any connection between circadian misalignment and disease.
Show answer
Answer: (B)
(A) overstates "associated with" as "proven to cause" — the passage explicitly flags that causation isn't established. (C) drops the longer-term risks the sentence lists. (D) reverses the claim entirely.
13. The author mentions "night-shift nurses" in paragraph 4 in order to:
- (A) criticize hospital scheduling practices.
- (B) provide a real-world example of a population researchers have studied for circadian health effects.
- (C) argue that nursing is a uniquely dangerous profession.
- (D) explain how the suprachiasmatic nucleus develops.
Show answer
Answer: (B)
The example follows a general claim about occupational circadian research and grounds it in a concrete, commonly studied group — a rhetorical-purpose question is asking what job that detail does in the paragraph's argument, not just what it states.
14. According to the passage, all of the following are mentioned as factors that influence circadian timing EXCEPT:
- (A) exposure to natural or artificial light
- (B) meal timing
- (C) blood type
- (D) body temperature fluctuations
Show answer
Answer: (C)
Light exposure, meal timing, and temperature fluctuation are each discussed as inputs to the circadian system; blood type is never mentioned anywhere in the passage — the classic negative-factual trap is an option built from real-sounding but unstated content.
15. Look at the four squares [■] that indicate where the following sentence could be added to paragraph 2: "Light is the strongest of these signals, which is why sudden time-zone changes are so disruptive." Where would the sentence best fit?
- (A) Square 1
- (B) Square 2
- (C) Square 3
- (D) Square 4
Show answer
Answer: (Depends on placement — choose the square immediately after the sentence listing the different timing signals the suprachiasmatic nucleus receives)
The phrase "the strongest of these signals" only makes sense once multiple signals have already been listed — place it right after that list, not before.
16. Directions: An introductory sentence for a brief summary is provided: "The body's internal circadian clock coordinates many biological processes, and disruption of this system carries real health consequences." Select the THREE answer choices that express the most important ideas in the passage.
- (A) The suprachiasmatic nucleus acts as the body's master timekeeper.
- (B) Circadian misalignment is linked to both short-term and long-term health risks.
- (C) Coffee consumption can temporarily mask symptoms of poor sleep.
- (D) Shift work is a common real-world cause of circadian disruption.
- (E) The circadian clock was first identified in fruit flies.
- (F) Some cultures have historically napped twice a day.
Show answer
Answer: (A), (B), (D)
These three map to the passage's core structure: what the clock is (SCN), why disruption matters (health risks), and a concrete real-world cause (shift work). (C), (E), and (F) are not part of this passage's actual content.
