@shafieiava,

Let's look at (B) and (C).

(B) says, "Over the last several years, the market for computer games
has grown steadily, but Ditalgame's share of that market has shrunk
considerably."

The issue with (B) is that this could be caused by the widespread
piracy of Ditalgame's games. However, it's also possible that they
simply make bad games. Thus, (B) requires an additional assumption in
order to make sense. On its own, it's not providing us with any
additional evidence to make us think that sales will increase, so it's
out.

(C) says, "The copy protection feature causes a copied game to be
playable just long enough for most people to come to enjoy it so much
that they decide they have to have it."

The second assumption made in the argument is that the people who
cannot illegally copy the game will purchase it. (C) strengthens this
assumption, as it tells us that the copy protection feature gives
people a glimpse of the game just long enough so that they feel like
they have to have it, so (C) is the correct answer choice.

Does this make sense? Let us know if you have any other questions!
