dose this sentence make s statement or gives a command.

A command is this:

Study the problem carefully.

(The subject is understood, not stated.)

so its a statement right

Yes, a statement.

To determine whether the sentence "I think it would be best to study the problem carefully" makes a statement or gives a command, we can examine the structure and content of the sentence.

First, let's break down the sentence:

- Subject: "I"
- Verb: "think"
- Object: "it would be best to study the problem carefully"

Based on this breakdown, we can see that the subject ("I") is expressing an opinion or belief ("think") about the following statement ("it would be best to study the problem carefully"). Therefore, this sentence is making a statement rather than giving a command.

If the sentence were a command, it would be structured differently. For example, a command version of the sentence could be "Study the problem carefully." In this case, the verb ("study") is used in the imperative form, indicating a command.
