Self-study
Because people are generally better at detecting mistakes in others' work than in their own, a prudent principle is that one should always have one's own work checked by someone else.
Summary
People are generally better at finding mistakes in others’ work than in their own. So, one should always have their work checked by someone else.
Strongly Supported Conclusions
One should always have someone check their work because it is easier to spot mistakes in work that is not their own.

Which one of the following ████████ ███ ████ ████████████ ██ ███ █████████ ██████
a
The best elementary ██████ ████ ████████ ███ ███ █████ ███ ████ ████ ███ ██████ █████ ████████ ███ ███ ██ ████████ ███████ ████ ██████████ ███ ██████ ████ ██ ███████ ████ ██ █████████
There is no mention of someone checking someone else’s work.
b
One must make █ ███████ ██████ ██ ███████ ███████ █████ █████ ██ ███████ █████ ██████ ████████ ████ ██ ██████ ██ ██████████ █████ ███ █████ ████ ██ ██████████ ███████ ██████
Although someone expresses their “view” to someone else, there is no mention that it is “checked” or vetted in any way.
c
Juries composed of █████ ████████ ██████ ████ ██████ ██ ████████ ██████ ██ ███ █████ ████████ ██ █████ ████████████ ██████ ███ ███ ███ █████ ███████ ███ ██ █ ██████ ████████ ██ ██████ ████ █████ █████████ ██ ███████ ████ ███ █████ ████████
This is close, but still not correct. Nobody checks the jury’s work for review.
d
People should always ████ █████ ███████ █████████ ██ ███████ █████ ███████ ███ ████ ███ ████ ██ ███████ ████ ██ █████ ██ ██ ████ ██ ██ █ ██████ ████████ ██ ████ █████████████ ███████
This is an accurate illustration of the principle. Someone’s writing (work) is checked by someone else. And this is done because other people can more easily spot mistakes.
e
Two people going ███ ███ ██████ ████ ████ █ ████ █████████ ████ ██ ████ █████ ███ ████ ██████ ██ ████████ ███████ ████ ██ ███████ ███ █████ ███████ ██ ██ ███ ███ ████████ ██████ ████████████
There is no “checking for mistakes” here. Also, the following sentence is completely unrelated to the principle in the stimulus.
