It's a figurative (i.e. not literal) expression which means "to overwhelm". It can be used both in a positive and negative sense. Blow, in a literal sense, can take form as a noun, which can mean a hit or strike on someone or something (e.g. I took a blow to the head). As a verb, blow would usually mean to produce a current of air (e.g. the wind blows or blow air through your mouth). Of course, this is not a comprehensive list as the word 'blow' can be used in a whole range of contexts.

Yes, you scored 15 points out of the possible 25.

It basically means 'drunk'. Wine, or alcoholic drinks in general, impair one's senses.

Social has a wider range of meanings, it can mean: 1. To enjoy the company of other people (e.g. I am a social person) 2. It can refer to events that are quite formal or of a sociable standing (e.g. I am going to this social event) 3. It can relate to the study of people in society (e.g. The social status of the working class) Gregarious does have a similar meaning to sociable, but what I would say is that the word 'gregarious' is not often used in conversational English; it is more of an academic word (at least in my opinion).

It would sound better if you split this structure into two. I just read the latest issue of xx magazine. One of the articles talked about how some of our foods are bad for dogs.

Correct (adjective) means true, accurate, right (e.g. I am right) etc. etc. Correct (verb) i.e. 'to correct' is similar in meaning as rectify (e.g. I want to rectify this mistake. I want to correct this mistake.)

For me, the use of the phrase 'well into' is used incorrectly in this example. Generally, the phrase 'well into' means that you are 'far along' a process, action or timescale. For example, age. If I was 35 years old, you could say that I am 'well into' my 30s. Another example, If I had 6 exams scheduled this summer, and I have finished 3 exams - I am well into my exam schedule. But the phrase 'well into his 35s' does not make much sense to me. I hope that helps a little.

The word 'talk' is often used in the context of a conversation with other people, that's why it makes more sense to say "Let's talk about this particular subject". 'Speak' is often used to describe the action of communication, and this can sometimes imply a one-sided dialogue (e.g. I am going to speak to her").
