Explanation:

First Question:

To determine the type of drugs that includes cough medicine which can be misused, we analyze each option:

• Option a: Illegal drugs are substances that are prohibited by law, and cough medicine is not typically classified as illegal.
• Option b: Over - the - counter (OTC) drugs are available without a prescription. Many cough medicines are OTC and can be misused (e.g., taking more than the recommended dose for non - medical reasons).
• Option c: Nutritional supplements are for nutritional purposes, not for treating coughs, so this is incorrect.
• Option d: Prescription drugs require a doctor's prescription, while many cough medicines are OTC, so this is not correct.

To find what long - term substance use can lead to that makes it harder to stop, we analyze each option:

• Option a: Long - term substance use generally does not lead to sleep improvement; in fact, it often disrupts sleep.
• Option b: Long - term substance use is more likely to impair focus rather than increase it.
• Option c: Addiction is a common result of long - term substance use. Addiction involves physical and psychological dependence, which makes it very hard to stop using the substance.
• Option d: While some substances may cause weight loss, this is not the main consequence that makes it hard to stop using; addiction is the key factor here.

Answer:

b. Over - the - counter drugs
