Questions: Teens from low-income families who use multiple types of drugs and commit crimes frequently are studied. Which common characteristic among persistent substance abusers and criminals is illustrated? Poor school performance Rational choice Emotional problems Genetic basis

The answer is Poor school performance.

Explanation for each option:

• Poor school performance: This is a common characteristic among persistent substance abusers and criminals, particularly in teens from low-income families. Poor academic achievement can lead to a lack of opportunities and increased likelihood of engaging in risky behaviors, including drug use and criminal activities. Studies have shown a correlation between academic struggles and higher rates of substance abuse and delinquency.

• Rational choice: This theory suggests that individuals weigh the costs and benefits before engaging in criminal behavior. While it can apply to some criminal activities, it is less likely to be a common characteristic among teens from low-income families who are persistent substance abusers and criminals, as their actions are often influenced by environmental and social factors rather than calculated decisions.

• Emotional problems: While emotional problems can contribute to substance abuse and criminal behavior, they are not as universally observed as poor school performance in this demographic. Emotional issues may exacerbate the situation but are not necessarily a common characteristic across all individuals in this group.

• Genetic basis: Although genetics can play a role in predispositions to substance abuse and certain behaviors, it is not a characteristic that is commonly observed or easily measured in studies of persistent substance abusers and criminals, especially in the context of teens from low-income families. Environmental factors often have a more significant impact in these cases.
