Subject of a verb in sentence and two examples

Here can is the subject

Sits is the verb

2) the women who went to meetingwere bored

Here women is the subject

And were is the verb

Instead of "to get kids used to how to use a computer", you should change it to something like "to teach kids how to use a computer", After the word computer, I recommend that you start a new sentence, like this "...how to use a computer. They would also use video games...". After the word "Overall", you should add a comma.
