Difficulty: Easy
Correct Answer: Only assumption I is implicit
Explanation:
Introduction / Context:This problem tests the identification of minimum unstated beliefs (assumptions) that make a predictive statement reasonable. The claim links better programme quality to higher T.V. sales, implying a causal pathway through audience appeal and perceived entertainment value.
Given Data / Assumptions:
Concept / Approach:
Step-by-Step Solution:
The causal chain is: better programmes → greater viewer interest → higher perceived value of owning a T.V. → increased purchases.This chain presupposes T.V. is a meaningful entertainment medium (Assumption I). If T.V. were not attractive entertainment, better programmes would not materially change sales.Assumption II is not necessary. The statement is conditional (if quality improves) rather than factual (quality has already improved). The prediction can be made irrespective of whether improvement has yet occurred.Verification / Alternative check:
Keep I, drop II: The claim still stands as a forward-looking prediction. Keep II, drop I: Even if quality improved, sales would not rise unless people regard T.V. as worthwhile entertainment. Thus I is necessary; II is not.Why Other Options Are Wrong:
Only II / Either / Neither / Both misread the conditional nature of the statement or ignore the entertainment-value premise that drives sales.Common Pitfalls:
Confusing a conditional forecast with a report of current facts; assuming that a prediction requires present improvement.Final Answer:
Only assumption I is implicit
