Hello all,

Is this a grammar test or a vocabulary test?
Source: http://www.english-test.net/esl/learn/english/grammar/ei001/esl-test.php#one

Can you hear what he is ...?
a) saying
b) speaking
c) telling
d) talking

And why is the choice (a) true?

Thanks in advance
Nasr

You could say it's a grammar-cum-vocabulary test, Nasr. :)

You need option a) in this particular test question, because the other possible choices would need to be followed by a preposition or an object to make sense.

Examples:

Can you hear what he is speaking about?

Can you hear what he is telling you?

Can you hear what he is talking about?
