Passage preview

Born in 1886 in New York, the American naturalist Clarence Birdseye had an instinctive curiosity, a love of food, and a strong entrepreneurial streak. At the age of ten, he was hunting, selling live animals, and teaching himself taxidermy, the art of preserving and mounting the skins of animals. He studied science in college, but had to drop out because tuition was too expensive. Forced to support himself, he moved west, where he worked in Montana as an assistant naturalist, capturing small mammals to study the parasites that they often carried in their fur. Eventually, partly as a result of this research, the source of a prevalent disease was isolated.

Answers with explanations

  1. 1. college

    The note's **financial reasons** become **tuition was too expensive**, and **left** becomes **drop out**. What he dropped out of is **college**. Science is only the subject he studied there, so it isn't what he left.

  2. 2. disease

    Look for the work in Montana: he studied parasites in animal fur, and **partly as a result of this research** the **source** of a **prevalent** (= widespread) illness was **isolated**. So the gap needs **disease**. Parasites are what he studied, not what was found to be widespread.

  3. 2-3: blood

    2: Look for the work in Montana: he studied parasites in animal fur, and **partly as a result of this research** the **source** of a **prevalent** (= widespread) illness was **isolated**. So the gap needs **disease**. Parasites are what he studied, not what was found to be widespread.

    3: The note's **enjoyed** matches **relished**, and **such a harsh environment** matches **the cold climate and rugged landscape**. What he relished was **the challenge** of living there.

  4. 3. challenge

    The note's **enjoyed** matches **relished**, and **such a harsh environment** matches **the cold climate and rugged landscape**. What he relished was **the challenge** of living there.

  5. 3-4: H

    3: The note's **enjoyed** matches **relished**, and **such a harsh environment** matches **the cold climate and rugged landscape**. What he relished was **the challenge** of living there.

    4: Find the **Inuit** and ice fishing in the paragraph about food in Labrador. The note's **made a** is copied almost directly from the passage: he **made a powerful discovery** by accident, and it later led to flash freezing. So the gap needs **discovery**.

  6. 4. discovery

    Find the **Inuit** and ice fishing in the paragraph about food in Labrador. The note's **made a** is copied almost directly from the passage: he **made a powerful discovery** by accident, and it later led to flash freezing. So the gap needs **discovery**.

  7. 5. prisons

    The note's **so poor** matches **beneath the culinary standard**, and **couldn't serve it** matches **banned**. The places that banned it were **prisons**. Convicts appear in the same sentence, but they are the people who would eat the food, not those who serve it.

  8. 6. membranes

    Slow freezing made big ice crystals that **broke the membranes** around each cell. The note says flash-freezing kept them **intact**, which matches **flash freezing avoided this problem**. So the gap needs the plural noun **membranes**.

  9. 7. ink

    The note's **created a new kind of** matches **inventing**. The sentence lists two things he invented for the packaging: a glue, and then, after 'as well as', **a waterproof ink** for the labels. The note already gives glue, so the gap is **ink**.

  10. 8. FALSE

    The deciding words are **today** and **positive view**. The passage says that in the current age frozen food **has fallen out of favor with the public**, which is the opposite of a positive view, so the statement is FALSE. The later praise of frozen food comes from nutritionists, not the public.

  11. 9. NOT GIVEN

    The deciding word is **Most**. The passage mentions **fish caught in the North Atlantic**, but only to say they could be eaten in distant cities. **Summer** appears only with **produce harvested**, not with fish. Nothing says when most fish are caught, so the answer is NOT GIVEN.

  12. 10. FALSE

    The deciding word is **disagree**. Nutritionists would prefer fresh local food, but they still **acknowledge the value of frozen food**, and the university scientists **came to the same conclusion**. Both groups agree that frozen food is beneficial, so the statement is FALSE.

  13. 11. TRUE

    **Soon after being picked** matches **the minute a fruit or vegetable is harvested, it begins to decay**. Freezing then **locks in** the important **nutrients**, which means fresh produce that is not frozen loses them. The statement agrees with the text, so it is TRUE.

  14. 12. TRUE

    Both **Most** and **perfectly ripe** are matched: **most frozen fruits and vegetables** are frozen **within hours of their harvest, at their peak of ripeness**. The produce is picked when it is at its best, so the statement is TRUE.

  15. 13. NOT GIVEN

    The passage names **raspberries** and **vitamin C**, but only to compare frozen and unfrozen ones, which had nearly the same levels. It never ranks raspberries against other foods as a source of vitamin C. For TRUE or FALSE it would need to say how good a source they are, so the answer is NOT GIVEN.
