nope. in fact, there's no such thing as a verb that must be followed by "that"; you can essentially always follow such verbs with nouns, too, in the right context.
read here:
post47979.html#p47979also, there are often other idioms that work, too.
for instance, "found NOUN to be + description" is a perfectly valid construction. so, for this sentence, you could also write "a recent study has found amoxicillin to be as effective as..." -- as long as you wrote the second half in a way that's parallel to this.
Option A
amoxicillin, long a standard treatment for ear infections, as being about as effective as newer, more expensive antibiotics and causing
Also isn't the parallelism in option A is between "more expensive antibiotics and causing" rather than between "as being" and "causing"
whoa, no.
you can't split up "newer, more expensive antibiotics" -- that's one noun with 2 adjectives in front of it. when you have more than one adjective, they're separated by a comma (except in the case of really short words, like "big red truck"), but the whole thing is still one construction.
in option C
more expensive antibiotics and causes fewer side effects.
here the left part and the right part are both nouns right?
choice (c) creates a parallel structure with "
to be about as effective..." and "
that it causes..."
that doesn't work.
it can't be salvaged, since nothing on the left-hand side is parallel to "that it causes..."
again, you can't split up the construction "newer, more expensive antibiotics".
finally, "causes" here is a verb, not a noun.
in option d
more expensive antibiotics and with fewer side effects.
here left part is noun and the right part is prep phrase hence not parallel correct?
you're still splitting up the construction "newer, more expensive antibiotics".
but you are correct that nothing is properly parallel to "with fewer side effects".

honest evaluation time:
jp, from what you've posted here, it appears that your skill in parsing sentences (= figuring out which words are playing what role) is still somewhat deficient. in this sentence, you've (a) mistaken a verb for a noun, and also (b) tried to break up "adj + adj + noun" in the middle of the construction; before attempting SC sentences, you should at least get to a point where you don't make such mistakes.
i.e., it's ok to confuse things that are difficult to distinguish (e.g., the different kinds of -ING); that happens from time to time. however, if you have trouble distinguishing between nouns and verbs, you should take a few weeks/months away from the gmat and just
read a bunch of stuff in english, in order to become more comfortable with the language in general.
