If you are having trouble finding the subject in the sentence, try getting rid of all the words that you don't really need in the sentence. If you look at the first sentence, you can see that you don't really need the words "who is a great speaker" to understand the sentence. If you get rid of "of high employment in the disabled community and what to do about it" you still have a strong simple sentence. So what you should try to do when figuring out the subjects and verbs in a long sentence is to find the simple sentence within the longer one.

More things to remember about subjects:

• lists within a subject that are joined by "and" make the subject plural.

My best friend, her sister and I are going to the movies.

• lists within a subject that are joined by "or" have the same number (singular or plural) as the part of the subject closest to the verb.

I don't know if my best friend's brothers or her sister is home.

I don't know if my best friend's sister or her brothers are home.

The following words need a singular verb because they describe one person, place or thing.

Everything on the menu tastes great.

Each of the books has a dustjacket.

Everyone hates the snow.

These words need a plural verb because they describe many things.
