Harry: Which one do you like ,left or right?
Correct: Which one do you like, left or right?

Explanation: In your sentence, watch out for the spaces between your words. However, the expression "left and right" means "in every direction, everywhere".

Examples:

1. During the earthquake, rocks are falling left and right.
2. The boxer is throwing punches left and right.

>>>

Harry: He can ride aski for ages.
Correct: He can ride a ski for ages.

Explanation: You should put spaces between words so, the reader could tell one word from the other.

>>>

Harry: I take off the right
Correct: I take off the right shoe.

Explanation: In this sentence, you haven't included the object of the verb. You're taking off the right of what? Hence, we added a sample item like "shoe" to complete the sentence.

However, the expression, "take off" means "to become popular, to be common".

Here are some examples:

1. His career as an actor took off after the "Harry Potter" movie was aired.
2. I've liked John Green as an author even before the movie, "The Fault in our Stars", took off.
