Question
In the question below, a premise is given, followed by three statements which may or may not be assumptions on which the passage lies. From the options below, choose the one that reflects the correct choice of assumptions that follow. Passage: Blue-light blocking glasses have become a massive retail trend across North America and Europe, as millions of office workers purchase them to prevent digital eye strain and improve sleep quality. However, a comprehensive new clinical trial published in a leading medical journal reveals that blue-light filters on spectacles have no significant impact on reducing eye fatigue or improving melatonin levels compared to standard clear lenses. Consequently, the demand for these specialized glasses is expected to plummet in these regions following the dissemination of this report. Statements: 1. The primary motivation for consumers in North America and Europe purchasing blue-light glasses is their perceived health benefits rather than their use as a fashion accessory. 2. The clinical trial’s findings will reach a significant portion of the target market and will be accepted as a credible source of information. 3. This new clinical trial is robust enough to outweigh or debunk any previous marketing claims or smaller studies that initially popularized the benefits of blue-light filtering.
Solution
Assumption 1 follows: The passage concludes that demand will "plummet" because a study showed no health benefits. This logic only works if we assume people were buying the glasses for health (eye strain/sleep) rather than just for style. If people bought them for fashion, the study wouldn't affect sales. Assumption 2 follows: For a report to cause a drop in demand, it must be assumed that the public will actually hear about the report and trust its results. If the market ignores or disbelieves the study, demand would remain stable. Assumption 3 follows: If there are other studies or popular beliefs still circulating that claim the glasses do work, the demand might not drop. The conclusion that sales will go down assumes this new trial is the "final word" or the most influential piece of information that will now guide consumer choice.
