Answer choice B

@shafieiava, Let's look at (B) and (D). This is a strengthen with a necessary premise question, so we can use the negation test to find the right answer. The correct answer choice, when negated, will wreck the argument. (B) says, "Earthenware figures were never used as children's toys in ancient Egypt." (B)'s negation would say, "Earthenware figures were sometimes used as children's toys in ancient Egypt." While it is necessary that the hippopotamus was not just a children's toy, it is not necessary that figures were never used as children's toys. The argument doesn't discuss other figures, so we don't care about them. Thus, (B) is too strong to be necessary, so it's out. (D) says, "The hippopotamus' legs were not broken through some natural occurrence after it was placed in the tomb." (D)'s negation would say, "The hippopotamus' legs were broken through some natural occurrence after it was placed in the tomb." If some sort of environmental factor such as a strong wind caused the broken legs on the hippopotamus, that would be an alternative cause. It's necessary to the argument that a natural occurrence isn't the explanation. (D)'s negation wrecks the argument, so (D) is the correct answer choice. Does this make sense? Let us know if you have any other questions!

Why is A incorrect?

Hi @connordelacruz, A says the hippo was not found in the tomb of a child. Its negation would say that the hippo WAS found in the tomb of the child. The argument hinges on the idea that the hippo was a form of protection from wild beasts in the afterlife. The fact that it was found in the tomb of a child would not impact the authors conclusion, presumably kids would need as much protection from beasts in the afterlife as adults would.
