i need help with this sentence, please, it's important :(

Hi,
is this sentence correct?

professor black considers that younger women are less prepared to deal with the sacrifices she has dealt with.

No, because you need to add two capital letters.

You would, of course, need an appropriate context in which to say this.

Best wishes, Clive

oh, there are some other things i wanted to ask...

- can you say that someone PERFORMED a speech. 'cause i wrote that in my exam and the teacher said she had never heard of that expression

- is the term 'fighter for human rights' correct? i know that activist would be a more appropriate word but still...

- is it ok to say 'the amount of women' 

 
i'd really appreciate the help, i'm from croatia and on our college there are some problems with the teachers. they give us these exams that are almost impossible to pass and i'm not sure that they actually know the answers :)

- can you say that someone PERFORMED a speech. 'cause i wrote that in my exam and the teacher said she had never heard of that expression
It's better to say someone gave a speech. You perform in a play.

- is the term 'fighter for human rights' correct? i know that activist would be a more appropriate word but still...
It doesn't sound natural at all. Human rights advocate, or human rights activist, as you suggest, is far better.

- is it ok to say 'the amount of women' 
No, say "the number of women."
 

You will find examples of just about everything on the Internet.

Are you really comfortable using Google searches as your basis for deciding something is acceptable?
