D
As per the conditions stated the final performance must be by a male acrobat. There are two male acrobats: F and G. In the answer choices only G is given. F is not mentioned. Therefore G could be the last of the artists to perform.
C
As per the conditions stated in the question, the first performance of the evening must be by a female artist. There are 2 acrobats H and I and two mimics L and M. Now if the last artist of the evening must be a male acrobat, as per the conditions and also the performance of acrobats and mimics must alternate throughout the evening, the first artist will necessarily be a (female) mimic. L is not mentioned in the answer choices. Therefore M could be the first of the artists to perform.
D
As per the conditions the last artist should be a male acrobat and the second artist must be male. Also the performance of mimics and acrobats should alternate, then the 2nd and last artists will be male acrobats and the 4th and 6th will be female acrobats. If H performs fourth, then I must perform sixth.
A
There are only 2 female mimics they are L and M. If M is to perform seventh then as per conditions stated, L will have to perform first.
B
If F is to perform eighth, then the second artist who should be a male acrobat as per the conditions stated in the passage. Therefore the second artist will be G.
D
As per the conditions stated, it follows that the third, fifth and seventh slots would be for mimics. Therefore if J were to perform third, K (mimic) must perform fifth or seventh.
B
If L performs third then as per the conditions stated M will have to perform first and J will perform seventh. Also the second and eighth artists are male acrobats. Now I (female acrobat) performs fourth. Therefore it follows that H must perform sixth.
