Self-study
One way to compare chess-playing programs is to compare how they perform with fixed time limits per move. █████ ███ ███ █████████ ████ █████ █ █████████████ ███████ ██ ███████████ ███ █████ █████ ████ ██████ ███ █████ ████ █ ███████ ████ ████ █ ██████ ██████ ██ ███████ ██ ███ ██████ █████████ ████ ██ ██████ ███████ ███ ███████ ████ ██ ████ ██ ███████ ████ ████████ █████ ██ ███ ████ ████████ ███ █████
Summary
One way to compare chess-playing programs is to compare how they perform a fixed time limit per move. This comparison is done by using any two computers that can run the program and giving each computer a set time limit to make a move. The faster computer will have a better chance of winning because the program can examine more moves within the same span of time and pick the best possible move.
Strongly Supported Conclusions
If two computers are running the same chess-playing software, the computer that can analyze the most available moves within a given time limit is most likely to win.

Which one of the following ██ ████ ████████ █████████ ██ ███ ███████████ ██████
a
If one chess-playing ███████ ███ ███████ ████ ████████ █████ ████ █ █████████ █████████████ ███████ ███ ██ ███ ████ ████████ █████ ███ ████ ████ ███████████ ███ █████ ███ ██████ ███████ ████ ████ █ ██████ ██████ ██ ███████ ████ ███ ███████
This sounds similar but presents a very different situation. This talks about two different programs running on the same computer. If there were two different programs, there would be many more confounding variables to make a comparison.
b
How fast a █████ ████████ ██ ███ ██ ██████ ██ █████ █████████████ ████████ ████████ ███ ███ ██ ████ █████████
The stimulus says that the speed of a computer dictates how many moves the computer can assess, but nothing says its speed has no bearing on what program it can run. For example, you probably couldn’t run a fancy program on a potato computer.
c
In general, the ████ █████ █ █████ █████████████ ███████ ██ ████ ██ ███████ █████ █████ ████ ███████████ ███ █████ ███ ██████ ███ ███████ ████ ███████ ████ ████
This captures exactly what the stimulus details. The faster computer can examine more moves and is thus better positioned to make better moves and win.
d
If two different █████████████ ████████ ███ ███████ ██ ███ █████████ █████████ █████ ███ ████ ████ ███████████ ███ █████ ███ ███████ ███████ ██ ███ ██████ ████████ ████ ██ ████ ██ ███████ ████ ████████ █████ ██ ███ ████ █████████
This is a very different scenario than the stimulus. This answer choice has two different computers and two different programs. You can only reach the same conclusion under the same conditions presented in the stimulus.

If a chess-playing ███████ ██ ███ ██ ███ █████████ █████████ ███ ██ ████████ ████ ████ ██ ███████ ████████ █████ ████ ███████ ██ ███ ████ ████████ ████ ████ ███████ ██ ███ ████ █████████ ██ ████ ████ ██ █████ ██████ ██ ███████ ██ ██████ █████████
There is no information on what would happen if a slower computer was given more time compared to a faster computer. You have to assume that the processing speed of the slower computer is exactly equal to the time difference given to the faster computer.
