Hello. I'll be grateful for your help.

1)Is the sentence OK: "The terms of the new contract were being discussed exactly when he called" (I mean, is the word "exactly" OK here?)
2)Is the word order correct in the sentence: "The contract at this time is being discussed."?
3)Is the sentence correct: "They were discussing the contract right then."?
Thank you very much for all your help.

1. It's OK. I'd either omit it or use the word "just" in its place.

2. I'd start out with "At this time, ... " rather than split up the subject and verb with this adverbial phrase.

3. Yes

Hello! I'm here to help you. Let's go through your questions one by one.

1) Regarding the sentence "The terms of the new contract were being discussed exactly when he called," the word "exactly" in this context is not necessary for conveying the intended meaning. If you remove "exactly," the sentence still makes perfect sense: "The terms of the new contract were being discussed when he called." However, adding "exactly" emphasizes that the timing of his call coincided precisely with the discussion of the contract.

2) Regarding the sentence "The contract at this time is being discussed," the word order is generally correct. However, it may sound more natural if you rearrange it slightly to say, "At this time, the contract is being discussed." Starting with "at this time" helps to provide context before mentioning what is being discussed.

3) The sentence "They were discussing the contract right then" is grammatically correct. The use of "right then" emphasizes that the discussion of the contract was happening at that precise moment.

In summary, here are the revised sentences:
1) "The terms of the new contract were being discussed when he called."
2) "At this time, the contract is being discussed."
3) "They were discussing the contract right then."

I hope this explanation helps! If you have any further questions, feel free to ask.
