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: Gardeners are being encouraged to let their lawns grow wild in summer as part of a campaign to promote biodiversity. Assumptions: I. Well-maintained lawns attract fewer organisms. II. It requires less effort to maintain a wild lawn.Solution
The premise talks about letting gardens grow wild to enhance biodiversity. I is a valid assumption as it tells us how lawns that are not wild have less biodiversity. Thus, (a) is the right answer.
