Consider the following sentence:
In one study, 83 percent of 140 male and female executives in variety of businesses report having a mentor when they were younger.
More specifically,
...(they) report having a mentor when they were younger.
I am confused with the grammatical structure of the sentence. My inference is
They report that they had a mentor when they were young.
It can be seen that the "having a mentor when they were younger" play role of object in that sentence.
I am confused with the sentence, especially with "having".
Perhaps, having a mentor when they were younger is a noun clause. I am not sure about it.
Thanks in advance.
