1. The formula for calculating ideal body weight (IBW) for men is IBW (kg) = 50 + 2.3 * (height in cm - 150). If a man is 180cm tall, what is his ideal body weight?

Correct answer: C

Rationale: Substitute the man's height (180cm) into the formula: IBW = 50 + 2.3 * (180 - 150) = 74kg.

2. A study finds a link between increased screen time and lower academic performance. What additional information would be most helpful in interpreting this finding?

Correct answer: B

Rationale: Knowing the specific types of screen activities participants engaged in would provide crucial context for interpreting the link between increased screen time and lower academic performance. For example, if the majority of screen time was spent on educational apps or programs, the impact on academic performance may differ compared to if the screen time was mostly spent on social media or gaming. Understanding the nature of screen activities can help determine the potential mechanisms behind the observed relationship.

3. Which type of isomerism arises due to differences in the arrangement of atoms around a double bond?

Correct answer: C

Rationale: The correct answer is C: Cis-trans isomerism. Cis-trans isomerism, also known as geometric isomerism, arises due to differences in the spatial arrangement of atoms around a double bond. In cis isomers, similar groups are on the same side of the double bond, while in trans isomers, similar groups are on opposite sides. This type of isomerism is specific to compounds with restricted rotation around a double bond, leading to distinct spatial arrangements and different properties. Chain isomerism (A) refers to isomers with different carbon chain arrangements, functional group isomerism (B) involves different functional groups, and stereoisomerism (D) encompasses all isomers that have the same connectivity but differ in spatial arrangement.

4. What is the main point of the passage?

Correct answer: C

Rationale: The passage clearly identifies human activities as the cause of climate change and emphasizes the need for global action, aligning with C.

5. The final sentence suggests that public discourse about AI should focus on

Correct answer: C

Rationale: The emphasis on "ongoing public discourse" and "the future of AI in society" suggests a call for open discussions and collective responsibility, aligning with C.

6. The phrase "disruptions to ecosystems" refers to

Correct answer: B

Rationale: The phrase suggests profound impacts on ecological balance and species interactions, aligning with B.
