Help me! Part2

Today, I have an English lesson, so I need to prepare for the lesson for my students.

I've already prepared an article about Steve Jobs, but I haven't completed questions about it.

I'm wondering if the English grammar is OK?

After reading the article, answer the questions.

Q2: What was there in front of at Apple stores around the world after he died?

S., and the Prime Minister of Great Britain.

I don't know which is natural?

I think "What was his occupation" is the better question. "What did he do" is too vague.

Q5: At what the age, did he become very rich?

Q6: At what age, did he first quit Apple?

He resigned more than once, the second time was shortly before he died.

Q7: Why did he started to work for Apple again, about a decade later?

Q8: Why did was he was respected by so many people?(or Why so many people respected him so much?) Which is more natural?

The first question is more natural.

A8: Because he had passion.(or He was passionate.)

"He was passionate" is more natural.

Which is more natural?

"What was his goal"

In this article, I found an unfamiliar expression.

In this case what does "IN HIS MEMORY" means?

"In his memory", or in someone's memory, means that something was done for someone's behalf after they passed away, usually to help remember them. This happens a lot with people who may have passed away from some disease, like cancer. Many times, charities are established in someone's name to raise money to research some disease that person may have had. For example, someone named John Doe passed away because he had cancer. His family, friends or colleagues may create the "John Doe Memorial Foundation" to raise money for cancer research. It is then that it can be said that the "foundation" was set up "in John Doe's memory." Other people then will remember John Doe when they donate to the foundation which has his name. Does that make sense?
