like vs. such as

[anguyen]

I've once heard the preference for "such as" instead of "like", is this a valid GMAT preference?

[Ben Ku]

Like is used to express "similar to" whereas such as is used to list examples.

This is incorrect:
Joe likes to play sports like baseball, football, and soccer.
(This means that Joe doesn't like to play baseball, football, or soccer, only those sports that are similar to it, like cricket, rugby, and water polo.)

This is correct:
Joe likes to play sports such as baseball, football, and soccer.
(This means that baseball, football and soccer are among the sports Joe likes to play.)
