Official Solution: Must be true • Some individuals in the field of research are brilliant We know that some individuals in the field of research, including Casper, are very successful. Since all very successful individuals are brilliant, it follows that some individuals in the field of research are brilliant. Therefore, this must be true. Must be false • Casper is hardworking but not brilliant. We know that all very successful individuals are both hardworking and brilliant. Since Casper is very successful, he must be both hardworking and brilliant. This makes the statement that Casper is hardworking but not brilliant must be false. Other options • Karen is very successful. Karen is hardworking and brilliant. However, we are told that all very successful individuals are hardworking and brilliant, but not that all hardworking and brilliant individuals are very successful. Therefore, this cannot be determined. • Hardworking and brilliant people often achieve great success. While we know that being hardworking and brilliant are important qualities for achieving great success, we are not given information about the rate of success among hardworking and brilliant people. Therefore, this cannot be determined. • Karen has achieved more success than Casper. Even though Karen is described as more hardworking and brilliant than Casper, this does not guarantee that Karen has achieved more success than Casper. Therefore, this cannot be determined. Correct answer: Must be true "Some individuals in the field of research are brilliant. " Must be false "Casper is hardworking but not brilliant." GMAT-Club-Forum-r2mz4mhd.png

a) Karen is very successful. 
The characteristics given are vital to achieve success but doesn't ensure success. Eliminate
 Must be True : Some individuals in the field of research are brilliant.   
Given that they are successful, they have to be brilliant in the field of research. Inferable. Must be True. 
 Must be False :Casper is hardworking but not brilliant.  since it is given that Casper is very successful in the field of research, we can successfully infer that he is both hardworking and brilliant hence it has to be false.

d) Hardworking and brilliant people often achieve great success. 
These are vital to achieve success but doesnt ensure success. Eliminate
e) Karen has achieved more success than Casper. 
We cannot infer this from the Q stem. Eliminate

Adit_ · Answer

Hardworking and brilliant are NEEDED to be successful.

So it means:
If successful, then hardworking and brilliant.
The stem does NOT say:
If hardworking and brilliant, then successful.
It is the other way round.

There is no information about hardworking and brilliant people that are NOT successful.

So that statement need not be true.
