It's been a rough life so far, … ?

Analyze the question: This is a question tag question. The tag must match the auxiliary verb and tense of the main clause, and it must have the opposite polarity (positive statement gets a negative tag).

Explain the concept:

• "It's" can be a contraction of either it is or it has.
• To decide which one, look at the words after it: • "It's + past participle / been" → it has • "It's + adjective / noun / -ing" → it is

Solution:

1. The sentence is "It's been a rough life so far."
2. "It's been" expands to "It has been" (present perfect tense), not "it is been," which would be ungrammatical.
3. The time phrase "so far" also signals the present perfect.
4. The statement is positive, so the tag must be negative. The auxiliary is "has," so the tag is hasn't it?

Checking the other options:

• B. hadn't it is past perfect and does not match the present perfect.
• C. isn't it does not match, because the clause is not "it is."
• D. wasn't it is past simple and does not match.

Correct answer: A. hasn't it

Tip: When you see "'s been", always expand it to "has been". Then use hasn't in the tag. Also remember: "so far," "already," "yet," and "just" often signal the present perfect.
