Information and Ideas practice question

A nutritionist claims that eating slowly leads people to eat less at a meal.

Which finding, if true, would most directly support the nutritionist's claim?

  1. A. In a controlled study, diners instructed to pause between bites ate about 10 percent less than diners told to eat at their usual pace, with identical food available to both groups.Correct
  2. B. People who eat quickly report enjoying their food more.
  3. C. Restaurants serve larger portions than they did twenty years ago.
  4. D. Diners told to eat slowly reported that their meals took longer.

Answer: A. In a controlled study, diners instructed to pause between bites ate about 10 percent less than diners told to eat at their usual pace, with identical food available to both groups.

Same food, pace manipulated, and the slow group ate less — that is direct support for pace causing lower intake.

Why the other answers are wrong

B. People who eat quickly report enjoying their food more.
Enjoyment isn't the claim; quantity eaten is.
C. Restaurants serve larger portions than they did twenty years ago.
Portion sizes over time have nothing to do with eating pace.
D. Diners told to eat slowly reported that their meals took longer.
That slow eating takes longer is true by definition and says nothing about how much was eaten.
