Explanation:

These are English grammar questions focusing on future tense forms (simple future with "will", etc.). Let's solve a few:

1. "as soon as she arrives" (present simple for future context) → simple future: will call
2. "by the end of the week" → future perfect: will have finished
3. "he’s busy" (prediction) → simple future negative: won’t come
4. "Will you..." → base form: join
5. "this weekend" (future) → "Will... visit"
6. "in a few months" (future) → "Will... buy"
7. Scheduled future (8 PM) → simple future: will start (or "are starting" for planned, but "will start" is common)
8. Prediction ("it will be warm") → simple future negative: won’t wear
9. "this year" (future) → "Will... take"
10. "talent show" (future event) → "Will... sing"
11. Promise ("I’ll bring a gift") → simple future negative: won’t forget
12. Question about future attendance → "will... attend"

Answer:

(for Q9 as an example, extend for others similarly):

1. will call
2. will have finished
3. won't come
4. join
5. Will; visit
6. Will; buy
7. will start
8. won't wear
9. Will; take
10. Will; sing
11. won't forget
12. will attend

(Note: For each, the tense is determined by context: time markers like "as soon as", "by the end", "this weekend", or purpose like promise/prediction/schedule.)
