1. I am not very comfortable seeing the second part underlined as it is used. Can you tell me if the writing as it is formed is correct? I got this sentence from a post.
I've browsed the internet, and this verb, seems to be specially used in things (that are ???) related to cars and things (that are ???) kind of technical.
2. Is this answer to a question correct with its preposition "at"?
What were you doing last night?
I was at ??? home eating dinner.
3. Don't you need an article in front of the words "right foot" and "left foot"?
continue with right foot, left foot ...
