Question

whats the paradox in this one i am not able to figure it out. Can some one

DanaJ · Answer

It's a better idea to simply post the question than an attachment, because of two reasons:
- some people won't download attachments
- our unregistered visitors won't be able to see the question

So the argument here goes like this:
- self-pollinating primroses seem to be more successful at the production of seeds
- however, they are rare

A does not really help explain the rarity of self-pollinating primroses. The fact that the insects don't discriminate between the two types is no new info, since we're already told in the argument that you can't distinguish between them.

B is correct, because this would help explain the success of non-self-pollinating primroses: their seeds are more robust and likely to produce a mature plant than those of the self-pollinating primroses. This happens even in conditions that are not favorable to non-self-pollinating primroses (lack of insects to carry the pollen) and that should tick the balance in favor of the other type. However, this is not the case.

C doesn't really address the paradox, since we're not comparing two types of self-pollinating plants, we're comparing those that can self pollinate and those that can't.

D might be true, but again does not explain the paradox. It needs to compare the two types!

E is already stated in the argument, so it's no new info. Again, no comparison between self-pollinating and non-self-pollinating.

Pheonix bhai,

Its just couple of minutes back i was throwing accolades for Dana wrt her LSAT CR prowess..Now that U saw that for real!!

@Dana, In my previous post (weakening the CR....The board of fredric muesuem CR) I was telling abt u, like how instrumental was your part for me to learn LSAT CR with dedication!!

thanks again
i need to work on my understanding of complex argument.
as far as the attachment is concern i am having some peculiar comps problem . I am unable to send a text message of large size . I think for my PC the def of large text is very small. If i have to do so then i will have to break down the CR in 5 -6 parts in oreder to send it without attachment.
and if i send any PM then it takes long time to get delivered .
i am unable to send any mails using my yahoo account...
i feel pity on myself and i leave in such a place where there is no service provider
lets hope i will be able to post this message without attachment...
apologies for the trouble...

@gmatmachoman: thanks for the kind words... I'm sure you'll do fine on GMAT CR as well!

@thephoenix: there's no inconvenience for me, but there might be some for you... As you might have noticed, the three questions that you've posted took a while to be answered! If you want your answers fast, you have to post them in the thread with regular text.

B is correct, because this would help explain the success of non-self-pollinating primroses: their seeds are more robust and likely to produce a mature plant than those of the self-pollinating primroses. This happens even in conditions that are not favorable to non-self-pollinating primroses (lack of insects to carry the pollen) and that should tick the balance in favor of the other type. However, this is not the case. --> B does not justify the word rare in last sentence of the argument.

C doesn't really address the paradox, since we're not comparing two types of self-pollinating plants, we're comparing those that can self pollinate and those that can't.

D might be true, but again does not explain the paradox. It needs to compare the two types!

--> B does not justify the word rare in last sentence of the argument.
Others are also not looking good.

@paes - The discrepancy within the argument is the number of seeds produced at different times. Hence B.

I picked up A

missed this part of the argument "you can't distinguish between self-primroses and others"

The discrepency is : Although the seed production average is higher in A(self-pollinating) than B, A plants are rare among total (A+B).

So B can justify that even the B-seeds are very few but its plants will be good enough.
But it cant justify why A- plants are rare.

Rather I would like to go for D. (If self pollination depends on soil condition, which I am not sure).

Others are also not looking good. --> I believe that B will be correct with following additional explanation. Argument says that "IN MANY YEARS ....." so we can assume that for a time span of 10years, 8-9 years come under scarce insect pollination. So, the word MANY is important here. Now if I add your explanation here than it justifies why self-pollinating plants are rare.
