The answer is (D). This question can be solved
Logically, by reading carefully and looking for hidden assumptions.
The argument can be boiled down to this: Since new games have detailed characters, they are harder to identify with, and thus they are less compelling. In other words we have there factors which lead to each other:
detailed characters > less identification > less compelling. While the first causation is explicitly explained (I
t is hard for players to identify with these figures, since the players can see that the figures represent other people ), the second isn't - it's only implied.
Thus, the answer must the assumption that lack of identification makes something not compelling. This is exactly what D tells us.
Another way to go about this is
reviewing the answers, and weighing where assuming each will lead us:
(A) There are no newer, more technically sophisticated video games in which the player controls the movements of a simple icon on the screen.
this doesn't help - we already know that this is true for most video games. Whether there are a few for which it isn't is unimportant to the general point being made(B) Most early video games in which the player controlled a simple icon on the screen were in other respects less compelling to players than newer video games.
This weakens the argument being made, which is that technical sophistication makes games less compelling(C) The technical sophistication necessary for creating detailed human figures in video games cannot in itself make those video games fully compelling even to players who identify with those figures.
this may strengthen the point made, but it is not necessary in order for it to be true. the argument is about the fact that people don't identify with players, not about the few who do.
(D) When players cannot easily identify with the figure or icon whose movements they control in a video game, they usually find that game less compelling than it otherwise would be.
this must be assumed - if not, the connection between the last two sentences is completely unclear: how does the fact that technology has lessened identification lead into technology making games less compelling? (E) If some aspect of a video game's technical sophistication makes it less compelling to players, then that video game contains a human figure with whom it is difficult for players to identify.
While this may be true, we don't need it to be: we need the opposite direction to be true: difficulty identifying leads to less compelling, not the reverse.
