1. What are they like?

-They are brave.

2. What is their presonality like?
- They are brave.

(Are the questions and answers right and the same?)

3. It is shaped like a fish.
4. They are shaped like fish.

(Are both grammatical? What is the part of speech of 'shaped' in the sentence?)

1 and 2 are fine, but correct the spelling error in #2.

3 and 4 are fine, too. The words "were shaped" make up the main verb; "were" is the auxiliary (helping) verb.

1. The question and answer are correct and the same. Both the question and the answer are focused on describing the subject as being brave.

2. Similarly, the question and answer are again correct and the same. Both the question and the answer describe the subject as having a brave personality.

3. Both sentences are grammatically correct. The phrase "It is shaped like a fish" is a statement about the shape of something, where "shaped" is a verb in the past tense, describing the action of shaping.

4. The second sentence, "They are shaped like fish," is also grammatically correct. In this sentence, "shaped" is an adjective modifying the pronoun "they," describing their fish-like shape.
