(N/A)

Question Stats:

0% (00:00) correct 0% (00:00) wrong based on 0 sessions
Choi: All other factors being equal, children whose parents earned doctorates are more likely to earn a doctorate than children whose parents did not earn doctorates.

Hart: But consider this: Over 70 percent of all doctorate holders do not have a parent that also holds a doctorate.

Which of the following is the most accurate evaluation of Hart’s reply?

A) It establishes that Choi’s claim is an exaggeration.
B) If true, it effectively demonstrates that Choi’s claim cannot be accurate.
C) It is consistent with Choi’s claim.
D) It provides alternative reasons for accepting Choi’s claim.
E) It mistakes what is necessary for an event with what is sufficient to determine that the event will occur.

Another one for B.

I was confused b/w B and E
E. It mistakes what is necessary for an event with what is sufficient to determine that the event will occur.

Hart does not state that having a parent who is a doctorate is sufficient to get a doctorate. Thus B.

I go for C.
Argument says that let's say 5 out of 10 would be D(doctor) (50% probability) from those whose parents are D and 400 out of 1000 (40% prob)of those whose parents aren't. Finally we have 405 D of whom obviously much more that 70% don't have parents D.

I feel that Hart's statement has nothing to do with what Choi said.
Choi just said that if my parent is a doctor, then, I am more likely to be a doctor as well. But Hart's statement has nothing to do with what Choi said.

A) It establishes that Choi’s claim is an exaggeration. - it does not
B) If true, it effectively demonstrates that Choi’s claim cannot be accurate. - not necessarily
C) It is consistent with Choi’s claim. -
D) It provides alternative reasons for accepting Choi’s claim. - no alternate reason provided
E) It mistakes what is necessary for an event with what is sufficient to determine that the event will occur.- the event was not necessary here.

So, by POE I choose C. If there was a statement that Hart's statement has o effect on Choi's statement, I would choose that.

OA is C.

This CR tests your understanding of numbers and scope shifts.

OE:
Whenever we see statements like more likely in CR we have to remember that it is testing some form of probability. So what Choi is saying is not that the children of doctors are guaranteed to earn doctorates, nor does he claim that they are likely to earn doctorates. He simply says that they are more likely (a higher probability) to receive a doctorate than those who do not have a parent with doctorates.

So if you pick numbers, as kandid has done above, you'll see that Hart's stmnt is actually consistent with Choi's claim.
