9. The successful education of children with speech defects involves ---- all means of approach. A) to explore
B) exploring
C) having explored
D) having been explored
E) to have explored

This question is taken from an official proficiency exam carried out in Turkey, UDS Health. It is clear that B works wonder here. The thing I wonder is whether C woıld be possible. I also would like to learn what conditions justify the usage of "having done", if used, after an active "involve" verb?

Thank you very much in advance.

Hi,

This question is taken from an official proficiency exam carried out in Turkey, UDS Health. It is clear that B works wonder here. Yes, that's my choice too.

The thing I wonder is whether C woıld be possible. Yes, in grammatical terms. However, in terms of meaning, the perfect participle suggests that the 'exploring' should be done before the 'successful educating' can be done. That meaning seems less suitable to me.

I also would like to learn what conditions justify the usage of "having done", if used, after an active "involve" verb? As I've indicated above, use such a thing when the participle's action precedes the action of the main verb.

eg He died, having fallen off a roof.

eg Finding a job as a teacher involves having gone to teacher's college (first).

Best wishes, Clive

Thank you Clive. You cannot believe how famous you are in my country for your such intricate explanations. As to using "having done" after involve, in the sentence above I thought it is possible to think that the successful education of children with speech defects requires the educators to have explored all means of approach. Is it so meaningless?
Hi Mamger,

It could make sense, if the speaker objected to educating children with speech defects, on the pretext that no means of approach have been found so far. Sounds too pessimistic, doesn't it?

Hi Mamger,

You cannot believe how famous you are in my country for your such intricate explanations. That's a very nice thing to say. I appreciate your words. I visited Turkey many years ago, and some Turkish people (in Selcuk) were very kind to my wife and to me. Tesekkür ederim.

Best wishes again, Clive
