2.The teachers have sent the book to the publisher.--past
3.The essay has been shortened by ten pages.-- past
4. This method of painting and drawing is effective for us. -- weak

What is your answer for 1?

Your answer for number 3 is wrong.

The other two are right.

I think # 1 is weak and #3 is weak.

To determine if the verbs in these sentences are in passive voice, weak, or past tense, let's break them down one by one.

1. "The book was informative but too long."
Verbs: was, informative, but, long
In this sentence, the verb "was" is in the past tense, while the adjectives "informative," "but," and "long" describe the book. Therefore, the verb in this sentence is in the past tense.

2. "The teachers have sent the book to the publisher."
Verbs: have sent
In this sentence, the verbs "have" and "sent" form the present perfect tense. This tense indicates that the action of sending the book to the publisher was completed in the past but has a relevance to the present. So, the verbs are not in the past tense, but rather in the present perfect tense.

3. "The essay has been shortened by ten pages."
Verbs: has been shortened
In this sentence, the verbs "has been" form the present perfect passive voice tense. The action of shortening the essay was done to it rather than being performed by someone actively. So, the verbs are not weak or in the past tense, but rather in the present perfect passive voice tense.

4. "This method of painting and drawing is effective for us."
Verbs: is, effective
In this sentence, the verb "is" is in the present tense, while the adjective "effective" describes the method. Therefore, the verb in this sentence is not weak or in the past tense, but rather in the present tense.

To summarize:
- Sentence 1 has the verb in the past tense.
- Sentence 2 has the verbs in the present perfect tense.
- Sentence 3 has the verbs in the present perfect passive voice tense.
- Sentence 4 has the verb in the present tense and is not weak or in the past tense.
