Question

nphelan · Answer

I opted for C, I was wrong. After reading this over about 5 times the only thing I can figure is that the statement reads "the human heart secretes a hormone, a substance that controls the amount of salt in the blood and volume of blood circulating within the body." Which after reading it a few times tells me that the Heart, in this case, only has one function, that is to release this hormone, the hormone itself controls everything else. so in this sense maybe the only thing that matters is that a mechanical pump can be substituted to released the hormone as well and therefore it will take care of itself.

Hopefully somebody else chimes in with their opinion on this one.

Thanks nphelan

mayansd · Answer

couldn't settle for an answer, as each option seemed too strong or not supported by the argument. And finding out the OA did shock me, as I had ruled out D straightforward. But after reading nphelan's post, D does make sense.

GMATmission · Answer

Even after reading the explanations, I am not able to understand the reasoning. Does anyone else has an opinion.

restore · Answer

I came to either answer A or D. I chose A, because I believed it actually had the most relevance to the passage. B, C, and E did not seem to fit "right" in my head.

I would also like an explanation that connects a mechanical pump (being utilized as an artificial heart) to topic of hormone secretion in the heart.

MBAhereIcome · Answer

the passage mentions only one function of heard i.e. to secrete hormone, therefore D looks like a winner. i actually chose E but then i realized that a drug can itself be the hormone, so it does not necessarily have to influence the heart to secrete the hormone.

however, the OA is still debatable because the source is unreliable.

malar · Answer

it is still not clear. Can anybody give sensible explanation for this as for me D is completely out of scope

DexDee · Answer

I chose E as well. Hormones seem to 'heavily influence' the blood pressure, therefore by controlling the hormone, the blood pressure can be regulated. In retrospect though, the passage does NOT say that controlling the hormone is the ONLY way to regulate the blood pressure. This weakens E.

D does not convince me fully. A mechanical pump can secrete hormones? Should it rather not be pumping blood at a fixed rate?

fluke · Answer

None correct. Please ignore this question unless author tells us the exact source and OE.
