Hello! Why doesn't Rob use the article in these sentences " it could be _tea. perhaps it's _tea."

Hello Prime,

The definite article isn't appropriate here because he's simply identifying that it is tea. An indefinite article isn't appropriate because the tea is not being mentioned for the first time, and in addition, indefinite articles aren't used with uncount nouns - in this case, 'tea' is uncount.

You can read more about all of this on our definite article, indefinite article and uncount nouns pages.

Hi rosario70,

Rob says 'A woman was lying on the floor and there was a teacup next to her' at that point, and Stephen says 'We might have run out of time, Rob'.

Hello Sir,
In question 4 of task 2, we have this sentence
"He must spend a lot of time practicing"

It looks like the speaker is giving advice to Adam. Is he giving advice or just saying what he thinks Adam might be doing?

Does this sentence mean the same as 'He must be spending a lot of time practising'?

Hello Adtyaggrwl,

In question 4 the speaker is not giving advice but is rather making a logical deduction about Adam based on the evidence he has. In other words, he sees that Adam is a good musician and speculates on the reason for this.

The choice of 'spend' or 'be spending' is a choice of simple or continuous forms. You can find more information on when to use continuous forms, and how they differ from simple forms, here.

Thanks for the clarification. But, in a different context, can the sentence 'He must spend a lot of time practising' also mean a suggestion?
