Below is another acceptable option:

Question(That), please.

Hi, there

Could you help me with a question?

You can use "that" in sentences like "This month's attack was much different than THAT of last year", can't you? Would it sound odd to use it in this paragraph?

"If this month's agreement has seemingly reduced the risks of a nuclear conflict on the same scale as THAT of the Cold War's WHICH the Cold War saw, it has surely increased the diffuse dangers of essentially rampant violence."

Why can't I use "that" here? "(...) reduced the risks of a nuclear conflict on the same scale as THAT(that SCALE) which the Cold War saw"?

Please, help me. Please

I can't go the theatre this weekend!

As always, you feedback and suggestions to make this letter more natural would be appreciated. Please ignore the possible mistakes in the Prompt. (the lines between the asterisks)

Dear David,

I hope you’re well. I’m writing to let you know that due to an unscheduled business trip, I won’t be able to come with you to the theatre this weekend. I’m truly sorry for telling you this at such a short notice and I hope you’ll accept my apologies.

The reason why I can’t come to the theatre is that I’ve been asked to visit a client in Germany to help with a product launch and I won’t be back until Monday. I wish I could have had known about this trip earlier but unfortunately my colleague who is in charge of product launches in the central Europe countries has been in a car accident and therefore I have to take care of his project commitments while he is in hospital.

What do you think about going to the cinema this week with Michael? As you know he is a cinephile and I’m sure he’ll be more than happy to join you. I thought I could offer my ticket to him and if you’d agree I could ask him to accompany you to the theatre. Once more, I’m sorry for not being able to come with you and I hope you’ll let me make it up to you by inviting you and Sara for dinner next Saturday after I come back from Germany.

Keep in touch
Adib
