Practice Reading: Multiple Choice, Single Answer ID: #37495 Stress Levels
Instructions ›
Read the text and answer the multiple-choice question by selecting the correct response. Only one response is correct.
Teens who have lived in poverty experience physical signs of stress at higher levels than those in more economically secure families. In an ongoing longitudinal study, researchers tested the saliva of 229 17-year-olds, many of whom had lived at or below the poverty level between the ages 10 and 16, for their levels of cortisol — a hormone in the blood. It is one of the commonest metrics for measuring stress. It showed that poverty in children has resulted in stress. Also, researchers examined cortisol levels after participants experienced a social stressor and their cortisol levels typically increase following stress.

Option 3: "presenting conclusion and supporting evidence."

Explanation: This option is correct because the author presents a conclusion about the impact of poverty on stress levels in teens and supports it with evidence from a longitudinal study, including specific data about cortisol levels. This aligns with the main idea of the text, which is to highlight the relationship between poverty and stress.

Option 1: "providing typical examples."

Explanation: This option is incorrect because the text does not focus on providing typical examples. Instead, it presents a specific study and its findings regarding the effects of poverty on stress levels in teens, rather than general examples.

Option 2: "following natural time order."

Explanation: This option is incorrect as the text does not follow a chronological sequence. It discusses a study and its findings without organizing the information in a time-based manner, making this option not applicable.

Option 4: "comparing opinions from different sides."

Explanation: This option is incorrect because the text does not compare differing opinions. It focuses solely on the findings of a specific study regarding the effects of poverty on stress, without presenting contrasting viewpoints.
