'a' is right if I am speaking during the match time,right?
Well, sort of, yes. If the question consisted of
only the second sentence, then yes. If you are watching the match and the score is 6-0 with ten minutes left, you can use the present continuous to say
Liverpool are winning easily.
The issue with this question is that the person who wrote it was thinking of the match as a future event. So, in order to try to make this clear, he/she added the first sentence, thinking that it would render answer 'a' as incorrect. In my opinion, the writer does succeed in doing that, though not as well as he/she could have.
But still, if the match is thought of as a future event, that still leaves 'b' and 'd' as correct answers.
I don't enjoy criticising teachers for writing poor test questions (which I don't tend to do without seeing the task instructions) because this is something I myself occasionally do and I know how hard it can be. However, in this case, the question doesn't seem to work as it lacks validity. The only defence I can imagine for it being at all valid would be that the teacher has spent some time with the students in distinguishing a difference of use between
will and
be going to with regard to
the nature of evidence upon which the prediction is based, and is trying to test understanding of this distinction.
What we usually teach is this:
- Use be going to to make predictions when there is present (or 'direct') evidence. This may be evidence that can be seen or heard, or otherwise witnessed with the senses.
- Use will to make predictions when there is no present evidence.
Based on the above very general rule of usage, the answer should be
will. Unfortunately, real usage is not so clear cut.
