    Behind the counter a shopkeeper or assistant would fetch each item in turn from shelves the customer could not reach, weigh out loose goods, add up the bill by hand and often write it down on credit to be settled later.

    The break with this ancient pattern came in 1916, in the American city of Memphis, when a grocer named Clarence Saunders opened a store he called Piggly Wiggly.
  3. 3

    the reason self-service made lower prices possible

    Show answer

    Answer: Paragraph C

    Why: Self-service reduced the need for assistants, allowing stores to save on labor costs and offer lower prices, which attracted more customers, as explained in Paragraph C.

    Where to find it · Paragraph C
    A store in which customers served themselves needed far fewer assistants, and the savings could be passed on as lower prices, which in turn drew still more customers.
  4. 4

    how the placement of goods encourages extra buying

    Show answer

    Answer: Paragraph D

    Why: Paragraph D explains that the strategic placement of goods, such as placing staples at the back and profitable items at eye level, encourages extra buying by making customers pass by more products.

    Where to find it · Paragraph D
    Everyday staples such as milk and bread were placed at the back, so that customers had to walk the length of the shop, past hundreds of other products, in order to reach them.
  5. 5

    the growing importance of packaging and brand names

    Show answer

    Answer: Paragraph E

    Why: Paragraph E explains the growing importance of packaging and brand names by stating that items had to sell themselves directly from the shelf, leading manufacturers to focus on striking packaging and strong brand names.

    Where to find it · Paragraph E
    With no assistant to describe or recommend a product, each item now had to sell itself directly from the shelf, and so the look of the packaging and the strength of the brand name became enormously important.

Tips for the question types in this test

Matching Information

  • Read each statement and identify exactly what kind of information you are looking for — a reason, a result, an example, a definition, a contrast.
  • Note that the statements do NOT follow paragraph order, so treat each one as an independent search.

Common trap: Assuming the questions run in order — they do not, which makes linear reading inefficient.

Full Matching Information strategy

Summary Completion

  • Read the full summary first and identify which passage section it covers.
  • Predict the grammar and meaning required in every blank.

Common trap: Choosing an option only because it repeats a passage word.

Full Summary Completion strategy

Multiple Choice — Multiple Answers

  • Underline exactly how many answers are required.
  • Locate the relevant passage section and read its full scope.

Common trap: Choosing too many or too few answers.

Full Multiple Choice — Multiple Answers strategy

True / False / Not Given

  • Read the statement first and underline the key idea, especially any qualifiers like "all", "only", "never", "always", "more than" or dates and numbers.
  • Because the questions follow the order of the passage, scan for the paragraph that deals with the same topic rather than re-reading everything.

Common trap: Confusing "False" with "Not Given": choose False only when the passage actively contradicts the statement; if the passage is silent, it is Not Given.
