party of life - Probably a mistake. Probably intended to be "life of the party". A person who is very extroverted and entertaining and is therefore usually the center

Hi CJ,
I had composed a similar reply. But, I couldn't effectively co-relate them to the vocabulary-test, especially the third one. So, I left it out.
Looking at your post, this is what I would conclude:
A person who socializes very less has a very less vocabulary. On the other hand, the one who is an extrovert has the highest vocabulary.

Please tell me if I am wrong.

Yes. Well, as you have seen, I didn't even attempt to make any kind of connection.

Your hypothesis is worth exploring. Maybe vsuresh can shed some light on the issue by giving further details.

CJ

Thank you very much, CJ. I will wait for vsuresh to tell me more about this.

Thanks again,
Prajwal

Thank you, both of you.
I do not have the book before me now. But the phrases were given against the scores as I have given in my post.
Perhaps I think the meanings given CJ can be related to the level of the person's closeness with words just as it is with the people from the meaning of the phrases.

That was well-interpreted. Thank you very much!
