✔ Fred wasn't able to ride a bike when he was a child.

---
1. You mustn't tell anyone about this. *(allow)*

---
3. We weren't able to help him with his homework. *(can)*

> ✔ Explanation: "weren't able to" is equivalent to "couldn't" in the past.
---
4. It was necessary to write the essay again. *(have)*

---
5. It wasn't possible to buy that house. *(able)*
→ "Wasn't possible" = inability → "were not able to"
✔ We weren't able to buy that house.
> ✔ Explanation: "It wasn't possible" = "we couldn't" or "weren't able to".
---
6. You aren't allowed to take these books home. *(must)*
→ "Aren't allowed to" = prohibition → "mustn't"
✔ You mustn't take these books home.

→ "Found" = succeeded in doing something → "managed to find"

Let’s go through the conversation carefully.
---
A: Are you able to come out tonight? I’ve got tickets for that concert you wanted to see.
B: I'm not 1 ________ to go out because I was late in last night. Also, I 2 ________ stay in and look after my younger brother because my parents 3 ________ to go out earlier.
Let’s fill in:
- 1: “I’m not ___ to go out” → likely “allowed” or “able”? But context says “because I was late in last night” → probably allowed (punishment).
✔ 1. allowed → "I'm not *allowed* to go out"
- 2: “I ___ stay in…” → obligation → have to
✔ 2. have → "I *have* to stay in"
- 3: “my parents ___ to go out earlier” → they needed to leave early → had to
✔ 3. had → "my parents *had* to go out earlier"
---
A: Do you think your sister 4 ________ be able to look after him instead?
→ This is a question about possibility/future ability → use will
✔ 4. will → "Do you think your sister *will* be able to..."
---
B: I'll ask her but if she can't I 5 ________ have to stay here. Sorry.
→ Conditional: if she can't, then I will have to stay → future obligation
✔ 5. will → "I *will* have to stay here"
---
A: OK, no problem. Perhaps Jenni would like to come with me. She wanted to see them last year but didn't 6 ________ to go because she 7 ________ to go away that week.
- 6: "didn't ___ to go" → she wanted but couldn't → get? No. "Didn't manage"? Wait — common phrase: didn't get a chance? But we need one word.
Wait — perhaps: didn't manage? But only one word.
But the structure is: "didn't ___ to go" → likely have → "didn't have to go"? That doesn’t make sense.
Wait — let’s read: "She wanted to see them... but didn't ___ to go..." → she didn't get the chance? But again, one word.
Better: didn't manage? But "manage" is not a modal verb. But we are filling gaps with one word.
Wait — maybe could? But "didn't could" is wrong.
Wait — what about be able? But that’s two words.
Wait — perhaps have? "didn't have to go"? But that means she didn't need to go — contradicts wanting to go.
Ah! The correct expression is: didn't get a chance — but we need one word.
Wait — look at the pattern. Maybe: didn't manage → but again, “manage” is not used with “to” in negative?
No — “didn’t manage to go” is correct.
But the blank is one word. So we need a single word that fits.
Wait — perhaps could? But “didn’t could” is grammatically wrong.
Wait — perhaps the intended word is manage?
But “didn’t manage” is fine, but the blank is after “didn’t”, so it’s:
"didn't _______ to go"
So the verb must be manage → “didn’t manage to go” → YES!
✔ 6. manage → "didn't manage to go"
Then: 7. had to go away that week → explanation: she had to go away → couldn't go to the concert.
So:
✔ 7. had → "she *had* to go away that week"
