Question
In each question a statement is given, followed by two
assumptions, numbered I and II. An assumption is supposed or taken for granted. You have to consider the statement and assumptions and decide which of the assumptions is implicit in the statement. Statement: Health experts have advised the government to impose stricter regulations on the sale of junk food near schools, citing rising cases of childhood obesity. Assumptions: I. Easy access to junk food contributes to childhood obesity. II. Children frequently buy junk food from shops located near schools.Solution
The statement says health experts want stricter regulations on junk food sales near schools because of rising childhood obesity. This makes sense only if they assume that junk food consumption contributes to obesity → Assumption I is implicit. They specifically mention regulating shops near schools, which implies that children often buy junk food from these nearby outlets → Assumption II is also implicit. Since both assumptions are required to justify the recommendation.
