Besides adding complementary flavors to many foods, hot sauces stimulate the release of endorphins in the brain, just as exercise does, and these have a pain-relieving effect like morphine's.

hot sauces stimulate the release of endorphins in the brain, like exercise, and they have a pain-relieving effect that is like morphine
hot sauces and exercise both stimulate the release of endorphins in the brain, and they have a pain-relieving effect like morphine

the release of endorphins in the brain is stimulated by hot sauces, just as with exercise, and these have a pain-relieving effect like that of morphine
it's one of the worst official problems i've seen ... but we have to learn from it
(a)
* poor parallelism. (a correct gmat choice would almost always include much closer parallelism, such as ...they do blah blah blah, like exercise, and they do blah blah blah, like morphine)
* can't use 'these' as a standalone pronoun. (this/that/these/those are only acceptable as adjectives - these people, that hypothesis, etc. - or as part of parallel constructions - the symphonies of beethoven vs. those of bach, etc.)
(b)
faulty comparison (a pain-relieving effect is compared directly to morphine, rather than to the pain-relieving effect of morphine as obviously intended)
