The correct answer is "Have you been watering the plants?" This is an interrogative sentence in the present perfect continuous tense. It is formed by using the auxiliary verb "have" followed by the subject pronoun "you" and the main verb "been watering" in the present participle form. The present perfect continuous tense is used to talk about an action that started in the past, is still ongoing, and may continue into the future.

The question is asking for the specific question word that completes the sentence "_______ have you been listening?" The answer "How long" fits grammatically and contextually, as it is a question word used to inquire about the duration or length of time. The response "I've been listening for 5 minutes" also supports this, as it provides the specific amount of time that the person has been listening.

The correct answer is "I have been working hard since the beginning of the week." The original sentence is grammatically incorrect because it uses the present simple tense ("I have working") instead of the present perfect continuous tense ("I have been working"). The present perfect continuous tense is used to describe an action that started in the past and is still ongoing. In this case, the action of working hard started at the beginning of the week and is still continuing.

The Present Perfect Continuous is used to describe an action that started in the past and is still ongoing at the present moment. This tense emphasizes the duration or length of time that the action has been happening. It is often used to talk about actions that started recently or actions that have a direct relevance to the present moment.

The correct answer is "She's been working a lot lately." This sentence is written correctly because it uses the present perfect continuous tense ("has been working") to indicate an action that started in the past and is still ongoing. The use of the contraction "she's" is also appropriate.

The given sentence "We have been thinking" is an affirmative sentence in the Present Perfect Continuous tense. It is formed by using the auxiliary verb "have" in the present tense, followed by the auxiliary verb "been," and the main verb "thinking" in the present participle form. The sentence indicates that the action of thinking started in the past and is still ongoing in the present.

The given correct answer "She has not been watching" is a negative sentence in the Present Perfect Continuous tense. It indicates that the action of watching has not been happening continuously up until now. The use of "has not been" suggests that the action started in the past and is still ongoing, but the subject, "she," has not been actively involved in the action.
