What are the two statements that together prove that: "Sandy is a country music singer."?
A. Sandy sings in a band. B. Sandy likes country music the best. C. Difficult music such as country and classical require a strongly trained voice. D. Sandy’s band plays country songs. E. Sandy has attended singing lessons for many years.
The two statements that will prove that Sandy is a country singer is A and D. These two statements can be used together to make people believe that Sandy sings country songs. It is true that Sandy may like country music the best, but there are also some people who love country music but are not singers. Letter C is also just stating a fact, but this is not related to Sandy at all.
Good singers can sing country and classical music with proper training, but how sure are we that Sandy is a good singer? E is just stating that Sandy has taken a lot of lessons, but this does not mean that Sandy sings country music. This explains why A and D are the best answers.
