d) no change is necessary.

Explanation:

The sentence reads: Bill, the foreman of the construction company, is concerned about the safety in the large building. They have had three accidents in the past week.  

This needs no change as the subject is talking about 'the company' as a whole. So, the subject will be taking the plural form, thus making the use of 'they" valid.

the correct answer is c. he speculates on what might happen at given points in the future in a world without people. alan h. weisman is an american author, professor, and journalist. authors organize their information with a purpose. they present their ideas in an organized way. this is called text structure. weisman uses text structure so as to improve overall comprehension and to prove his points.
