Studying for the LSAT / LR (Newton/Hooke)
« on: September 15, 2005, 06:10:00 PM »
 ??? ??? ???
Pls explain with details..

Shortly after Newton circulated some of his theories of light in 1672, his colleague Hooke claimed that most of those theories were based on Hooke's own work. A modern reader might interpret Newton's famous comment, "if i have seen further it is by standing on the shoulders of giants", as a conciliatory gesture acknowledging indebtedness to Hooke and other contemporary scientists for some of his therories. Conciliatory gestures acknowledging indebtedness were uncharacteristic of Newton, however, and in his day such allusions to "giants" typically referred to the ancient Greeks, not to contemporary scientists.

The statement in teh passage, if true, most strongly support which of the following?
a) Newton did not intend the quoted comment to be an acknowledgement that his theories of light were largely derived from Hooke's
b) Newton did not take credit for any advances that Hooke make in the theory of light
c) Newton did not believe that any of Hooke's theories of light were basd on those of the ancient Greeks
d) Newton intended to credit some contemporary scientists other than Hooke for some of teh advances tha tNewton made in the etheory of light
e) Newton was not familiar with Hooke's work on the theory of light
