I forgot to include the following sentences.

I was sorry for Thomas's bad result in Italian (in his Italian test?)
He got a very low mark.
He led (?) a merchantilist policy.
I behaved badly with (also towards) her.

I was sorry for Thomas's bad test results in Italian.


He got a very low mark.

He led (?) a merchantilist policy. <~~I don't understand this one. A person can write policy and enforce policy, but I'm not connecting with "led" here.

I behaved badly towards her.

To correct and include the missing sentences, you can say the following:

1. I was sorry for Thomas's bad result in Italian (in his Italian test?). - This sentence is asking whether the bad result was specifically in Thomas's Italian test or something else. If you are unsure, you can leave it as is.

2. He got a very low mark. - This sentence is written correctly and does not need any changes.

3. He led a mercantilist policy. - In this sentence, "merchantilist" should be corrected to "mercantilist" for the correct spelling.

4. I behaved badly with her. - This sentence is written correctly. However, if you want to express that you behaved badly towards her, you could replace "with" with "towards" to clarify your intention.

Remember to proofread your writing and ensure the correct spelling, grammar, and punctuation before submitting it.
