What this passage tests
This passage is tested with Note Completion (Q1–7), True / False / Not Given (Q8–13). Each section below gives the strategy for that question type, the answers, and the sentence that proves them.
Questions 1–7: Note Completion
Strategy: Predict the word class from the note, find the paraphrase of the note's keyword in the passage, then copy the answer exactly within the word limit.
“they froze them overnight, then trampled them to squeeze out the moisture, then dried them in the sun. This preserved their nutritional value - if not their aesthetic appeal”
The note needs the crop the Incas preserved, and the described process of freezing overnight, trampling and sun-drying was applied to potatoes.
“In 1851, railroads first began putting blocks of ice in insulated rail cars to send butter from Ogdensburg, New York, to Boston”
In 1851 insulated rail cars carried 'butter from Ogdensburg, New York, to Boston', so the gap is 'butter'.
“they could export meat across the oceans. In 1880, a shipment of Australian beef and mutton was sent, frozen, to England”
In 1880 'a shipment of Australian beef and mutton was sent, frozen, to England', so the gap is 'meat'.
“During the freezing process, crystals formed within the cells of the food, and when the ice expanded and the cells burst, this spoilt the flavor and texture of the food”
Freezing formed 'crystals... within the cells of the food', which burst and spoilt flavour and texture.
“He also introduced the use of cellophane, the first transparent material for food packaging, which allowed consumers to see the quality of the product”
Birdseye 'introduced the use of cellophane, the first transparent material for food packaging', which is the product named.
“Canned foods were rationed to save tin for the war effort, while frozen foods were abundant and cheap”
Canned foods 'were rationed to save tin for the war effort', so the gap is 'tin'.
“By the 1950s, refrigerator technology had developed far enough to make these appliances affordable for the average family”
By the 1950s 'refrigerator technology had developed far enough' to make appliances affordable for average families.
Questions 8–13: True / False / Not Given
Strategy: Judge the whole statement against the text. FALSE contradicts the passage; NOT GIVEN means the passage never addresses that specific claim.
The ice transportation business made some Boston ship owners very wealthy in the early 1800s.
“In the early 1800s, ship owners from Boston, USA, had enormous blocks of Arctic ice towed all over the Atlantic for the purpose of food preservation”
Boston ship owners towed Arctic ice across the Atlantic, but the passage never says the trade made them very wealthy.
A disadvantage of the freezing process invented in Australia was that it affected the taste of food.
“While the food frozen this way was still palatable, there was some deterioration. During the freezing process, crystals formed within the cells of the food, and when the ice expanded and the cells burst, this spoilt the flavor and texture of the food”
The process caused 'some deterioration', as crystals bursting cells 'spoilt the flavor and texture of the food'.
Clarence Birdseye travelled to Labrador in order to learn how the Inuit people froze fish.
“In 1912, a biology student in Massachusetts, USA, named Clarence Birdseye, ran out of money and went to Labrador in Canada to trap and trade furs”
Birdseye went to Labrador because he 'ran out of money' to trap and trade furs, not to learn Inuit freezing methods.
Swanson Foods invested a great deal of money in the promotion of the TV Dinner.
“In 1954, the company adapted some of Birdseye's freezing techniques, and with the help of a clever name and a huge advertising budget, it launched the first 'TV Dinner'”
Swanson launched the TV Dinner 'with the help of a clever name and a huge advertising budget'.
Swanson Foods developed a new style of container for the launch of the TV Dinner.
“This consisted of frozen turkey, potatoes and vegetables served in the same segmented aluminum tray that was used by airlines”
It used 'the same segmented aluminum tray that was used by airlines', so no new style of container was developed.
The US frozen food industry is currently the largest in the world.
“Today, the US frozen food industry has a turnover of over $67 billion annually, with $26.6 billion of that sold to consumers for home consumption”
The passage gives the industry's turnover but never says it is the largest in the world.
