9. Astronauts who
experience weightlessness frequently get motion sickness. The astronauts see
their own motion relative to passing objects, but while the astronauts are
weightless their inner ears indicate that their bodies are not moving. The
astronauts’ experience is best explained by the hypothesis that conflicting
information received by the brain about the body’s motion causes motion
sickness.
Which one of the
following, if true, provides the strongest additional support for the
hypothesis above?
A During rough voyages ship passengers in cabins providing a view of
the water are less likely to get motion sickness than are passengers in cabins
providing no view.
(B) Many people
who are experienced airplane passengers occasionally get motion sickness.
(C) Some
automobile passengers whose inner ears indicate that they are moving and who
have a clear view of the objects they are passing get motion sickness.
(D) People who
have aisle seats in trains or airplanes are as likely to get motion sickness as
are people who have window seats.
(E) Some
astronauts do not get motion sickness even after being in orbit for several
days.
这道题看了题目知道是Astronauts接受了两个相反的信息导致了运动病，但是怎么看出来A说的就是两个不同的信息呢？分别是什么呢？
29. The price of a
full-fare coach ticket from Toronto to Dallas on Breezeway Airlines is the same
today as it was a year ago, if inflation is taken into account by calculating
prices in constant dollars. However, today 90 percent of the Toronto-to-Dallas
coach tickets that Breezeway sells are discount tickets and only 10 percent are
full-fare tickets, whereas a year ago half were discount tickets and half were
full-fare tickets. Therefore, on average, people pay less today in constant
dollars for a Breezeway Toronto-to-Dallas coach ticket than they did a year
ago.
Which one of the
following, if assumed, would allow the conclusion above to be properly drawn?
(A) A
Toronto-to-Dallas full-fare coach ticket on Breezeway Airlines provides
ticket-holders with a lower level of service today than such a ticket provided
a year ago.
(B) A
Toronto-to-Dallas discount coach ticket on Breezeway Airlines costs about the
same in constant dollars as they did a year ago.
(C) All full-fare
coach tickets on Breezeway Airlines cost the same in constant dollars as they
did a year ago.
(D) The average
number of coach passengers per flight that Breezeway Airlines carries from
Toronto to Dallas today is higher than the average number per flight a year
ago.
(E) The criteria that
Breezeway Airlines uses for permitting passengers to buy discount coach tickets
on the Toronto-to-Dallas route are different today than they were a year ago.
被两个表达给搞晕了，死活分不清楚：请问B和C有什么区别呢？B说每张打折的机票价钱都跟过去的一样；
C说所有的全价票价格都和过去一样，这两个表达有什么区别呢？
还请知道的人帮我分析一下这道题吧，我想我选错可能就是对这两个表达没有弄清楚
