I would have given the same answer as the previous teacher, so it would seem you are not making yourself clear enough. Maybe you are talking about height, rather than thickness?

Phil's right: it's complicated. The sentence 'wait a minute' is not to be taken literally. In other words, it has nothing to do with time, or waiting for one minute. The meaning is: 'I don't agree'; or 'I am not sure I agree'; or 'Let's not jump to conclusions'; or 'Let's reconsider'; or 'I/you/we are making an assumption/reaching the wrong conclusion." etc. It is an indication that the speaker wants to rethink or reconsider something, or wants the listener to rethink or reconsider something, or that the speaker disagrees with something and/or needs more time to consider the issue. It could also mean: 'Stop, there's something wrong here.'

I agree with the previous two answers, although I think by 'all along' you mean 'all the time', in other words throughout the time that the party is going on, in which case you will say: '...all throughout the dancing/dance party...' or '...for the duration of the dancing/dance party."

Mostly, they mean exactly the same thing, but 'taking an interest' can sometimes indicate that you have started becoming interested in something, whereas 'interested in' can indicate a more active, ongoing interest.

As Candice says, yes, both are perfectly OK. If, though, someone asks you: "Where have you been?", you will answer them in the same tense as the question: "I have been on a trip." If they ask: "Where were you?", you will likewise answer using the same tense as the question: "I was on a trip." If there was no question, use whichever you like.

In this context 'the cucumber job' would refer to a dish or table decoration using cucumber. Used like this, 'job' is slang for something the caterer has been asked to make using cucumber. The word 'job' is often used like this in English informal speech. For example, if a bakery needs to deliver bread rolls to one client and tarts to another, the boss might say: "If you do the bread roll job, someone else can do the tart job.

You can say either: I have a person on the phone I think you would like to talk to, OR: I have a person on the phone WHOM I think you would like to talk to. (Note the correct - i.e. objective - form of the pronoun 'who') . And no, I don't think it sounds odd to say 'get service', but it may be more usual to say: But it's OK, our apartment can be serviced tomorrow/you can service our apartment tomorrow.

I think the correct question here is 'what is the correct usage (not the correct spelling)?' These sentences quoted above have to do with indefinite articles (a) and definite articles (the). If you know the file's name, you use the definite article (the name), but if you don't know the name of the file, you use 'a name' and 'a file'. Here are some examples of definite and indefinite articles: The dog that lives next door was being followed by a dog I had never seen before. The girl I was dating is now seeing a boy from the next town.
