1. We had to cook the turkey for six hours.

2. We had to cook the turkey in six hours.

3. We had to cook the turkey until six hours.

4. We had to cook the turkey from six hours.

5. We had to cook the turkey after six hours.

(#1 is right? What about the others? If we use other prepositions, can't we make correct sentences? Would you let me know what other prepositions we can use? Thank you.)

Yes. # 1 is right. It took six hours of cooking for the turkey to be completely cooked.

The other sentences have different meanings -- but are not usually used.
======================================
(Thank you for your help. Would you like to check the following?)

1. We had to cook the turkey for six hours. (correct)

2. We had to cook the turkey in six hours. (What does this mean? Does 'in' mean 'within'? And then is this sentence correct?)

3. We had to cook the turkey until six hours. ( If we use 'until 7:00' p.m. instead of 'until six hours',then this sentence is right?)

4. We had to cook the turkey from six hours. (If we use 'from 7:00 a.m.' instead of 'from six hours', then is this sentence correct?)

5. We had to cook the turkey after six hours. (If we use 'after 7:00 a.m. instead of 'after six hours', then is this sentence correct?)

2. We had to cook the turkey in six hours. (What does this mean? Does 'in' mean 'within'? And then is this sentence correct?) With "within" it's fine, yes.

3. We had to cook the turkey until six hours. ( If we use 'until 7:00' p.m. instead of 'until six hours',then this sentence is right?) yes

4. We had to cook the turkey from six hours. (If we use 'from 7:00 a.m.' instead of 'from six hours', then is this sentence correct?) Yes, but I'd say from 7:00 a.m. until 1:00 p.m.

5. We had to cook the turkey after six hours. (If we use 'after 7:00 a.m. instead of 'after six hours', then is this sentence correct?) yes

1. "We had to cook the turkey for six hours." - This sentence is correct. It means that the cooking process for the turkey lasted six hours.


2. "We had to cook the turkey in six hours." - This sentence is grammatically correct, but it has a different meaning from the first sentence. It suggests that there was a time constraint of six hours to cook the turkey. It implies that the cooking process needed to be completed within six hours.

3. "We had to cook the turkey until six hours." - This sentence is not grammatically correct. The use of "until" in this context is not appropriate. Instead, you can say "We had to cook the turkey until 7:00 p.m." to indicate a specific time.

4. "We had to cook the turkey from six hours." - This sentence is not grammatically correct. The use of "from" in this sentence is not appropriate. Instead, you can say "We had to start cooking the turkey at 7:00 a.m." to indicate a specific starting time.

5. "We had to cook the turkey after six hours." - This sentence is not grammatically correct. The use of "after" in this sentence is not appropriate. Instead, you can say "We had to continue cooking the turkey after 7:00 a.m." to indicate a specific point in time.

To summarize, the correct sentence is #1, while the other sentences have different meanings and are grammatically incorrect. It is important to choose prepositions that convey the intended meaning accurately.
