Which is the true statement?

1. Adjectives can answer the question: How?
2. Adjectives always precede the noun they describe.
3. A word which functions as an adjective in one sentence is an adjective in all sentences
4. none of the above is correct
Answer 1

How-questions are almost always answered by adverbs or adverbial phrases/clauses.

Can you give me an example of an adjective answering a how-question?

I can't i was thiking what kind of dog

Answer to the question 2 adjectives always precede the noun they describe

No.

Example:

The dog is muddy.

To determine whether statement 1 is true or not, let's go through the other statements as well:

Statement 2: Adjectives always precede the noun they describe.
This statement is not entirely true. While it is common for adjectives to appear before the noun they modify, there are cases where adjectives can also come after the noun. For example, in phrases like "the president elect" or "the city proper," the adjective follows the noun.

Statement 3: A word which functions as an adjective in one sentence is an adjective in all sentences.
This statement is not true either. The same word can have different functions in different sentences. For example, the word "fast" can be an adjective in the sentence "She is a fast runner," but it can also be an adverb in the sentence "He ran fast."

Given that neither statement 2 nor statement 3 is entirely accurate, statement 1, which states that adjectives can answer the question "How?", is the true statement. Adjectives can indeed provide information about how something is done or the manner in which it is done. For example, in the sentence "She walked slowly," the adjective "slowly" answers the question of how she walked.
