1) The correct answer is B) is cooking.
Since the subject is "my mom and my dad," which is plural, the correct form of the verb to use should be the plural form "are." However, the provided options only have one verb in the plural form. The correct option would be the present continuous form of "cook," which is "is cooking." Therefore, the correct sentence in the present continuous tense would be "My mom and my dad are cooking rice and vegetables."
2) The correct answer is A) Talk about actions happening now and temporary situations.
The present continuous tense is used to describe actions happening at the moment of speaking or as a temporary situation. For instance, "I'm studying English at the moment" or "She is working as a freelance writer for the summer."
B) Talk about actions that happened is incorrect because the present continuous is specifically for events happening right now, it is not suitable to talk about past events.
C) Talk about future events is incorrect as well because we use the present continuous for actions happening in the present, whereas future events are described using the future tenses.
3) The correct answer is C) is listening.
Since Bob is singular, the correct verb form to use is "is" (third-person singular). The present continuous form of "listen" is "listening." Therefore, the correct sentence in the present continuous tense would be "Is Bob listening to music?"
