Answers and Explanations

Answer 1: (E) Given that Emeri and Faza are in different pens. Option A can be true as: The puppies in pen 2 could be Emeri, Galzar, Darton and Ashi. The puppies in pen 1 could be Faza, Cumin and Burma. Option B can be true as: The puppies in pen 2 could be Emeri, Galzar, Darton and Ashi. The puppies in pen 1 could be Faza, Cumin and Burma. Option C can be true as: The puppies in pen 2 could be Emeri, Galzar, Darton and Ashi. The puppies in pen 1 could be Faza, Cumin and Burma. Option D can be true as: The puppies in pen 2 could be Emeri, Galzar, Darton and Burma The puppies in pen 1 could be Faza, Cumin and Ashi. Option E cannot be true as it means Cumin is in pen 2 and Faza is in pen 1. So, Emeri is in pen 2 along with Cumin. Darton and Burma have to be in different pens. But Galzar and Darton have to be together. Hence, this cannot be true.

Answer 2: (D)

Option A: The given group of puppies cannot be in pen 2 as Burma and Ashley cannot be together in pen 1. Option B: The given group of puppies cannot be in pen 2 as Burma and Ashi cannot be together in pen 2. Option C: The given group of puppies cannot be in pen 2 as if Darton is not kept in pen 2, then Galzar is kept in pen 1 and in this case Galzar is put in pen 2. Option D: The given group of puppies can be in pen 2. Option E: The given group of puppies cannot be in pen 2 as if Darton is not kept in pen 2, then Galzar is kept in pen 1 and in this case Galzar is put in pen 2.

Given that Emeri shares a pen with Faza. Option A is not necessarily true as: The puppies in pen 1 could be Emeri, Faza and Burma. The puppies in pen 2 could be Galzar, Darton, Ashi and Cumin.

Option B is necessarily true as Galzar and Darton have to be together and given that Emeri and Faza are also together. Also, Ashi and Burma have to be in different pens. So, Cumin must be in pen 2, which has four puppies.

Option C is not necessarily true as: The puppies in pen 1 could be Galzar, Darton and Ashi. The puppies in pen 2 could be Emeri, Faza, Cumin and Burma.
