• B. HFCS is cheaper to use than sugar.
• C. HFCS is now used to sweeten a variety of products.

Detail C is supported by the text, which mentions that HFCS is now used to sweeten a variety of products. However, detail D is never discussed in the passage, making it the correct answer.

What does the word 'obligatory' mean in the context of the passage on Daylight Savings Time?

• A. Approved.
• B. Sparse.
• C. Requisite.
• D. Aberrant.

Correct Answer: C
Rationale: In the passage, Daylight Savings Time is presented as something that must be done by law, making it a requirement or something obligatory. 'Requisite' fits this meaning. 'Approved' (choice A) does not convey the sense of necessity as 'obligatory' does. 'Sparse' (choice B) means thinly dispersed and does not relate to the context. 'Aberrant' (choice D) means deviating from the norm, which is not applicable in this context.

Dr. Brian Schwartz's quote highlights the link between environmental exposure and cognitive decline, framing the entire discussion around the potential health ramifications of such exposure over time. This clearly aligns with choice A, making it the main idea of the passage.
