Cause they didn’t do what he wanted
Basically twice means 2 in these sentence twice means more than he earn in short words he wants to say that he wants to earn more than he is earning now
for example someone is earning $500 every month so he want to earn $1000 every month
I am guessing on this, but I think that the answer is the body.
B.
Not A. because it isn't only for solving simple problems.
Not C. because it CAN work well with personal or school problems.
Not D. because you can't solve a problem before their is a problem.
I hope this helped.
I dont understand your question, which statements??
