Which parallelism is correct to use? (A) in seems to to be logical because the formula is easy to use because it uses less variables is covered in the first stem.
Whereas, in (B): (1) that uses less variables
(2) that is easy to use
"Mario developed a developed a formula
(2) that is easy to use" in this it is not covering the (1) part which the reason why the "formula" is easy to use.
AndrewNThese are some strange-looking sentences,
lakshya14, each with its own double
developed. I should point out, too, that
variables are countable, so
fewer is more apt than
less. Although either sentence could pass for a legitimate one, it would take an overhaul to get it to that point. My rewrites:
A.2) Mario developed a formula that uses fewer variables and is therefore easy to use. (Note the lack of a comma and the addition of
is.)
B.2) Mario developed a formula that uses fewer variables and [that] is easy to use. (The
that need not be repeated, although it is not incorrect to put it in the sentence. Since the predicate within the embedded clause (the part from the verb on) is relatively short, we can carry over the
that as an understood element at the head of the second branch in
that X and Y.) If we inserted additional information about, say, the variables, then I would expect to see another
that:
B.3) Mario developed a formula that uses fewer variables, greatly improving the efficiency of any software that incorporates it, and that is easy to use.
Without the second
that in this last sentence, the reader might anticipate another
it instead, and there could seem to be a gap that would prove distracting.
I hope that helps with your query. Thank you for thinking to ask.
