Qn:1)the size of a male cycad cone is directly influences..
Answer is in the 11th line of the passage...
"Still, many male cycad cones are comparatively small and thus produce far less pollen"
Size propotional to amount of pollen
Correct Ans:(E) The amount of pollen produced by the male cone


Qn:2) Which is true of the structure of cycad cones?
The structure of cycads male cones is quite consistent with the wind dispersal of pollen,
clouds of which are released from some of the larger cones.
Answer is in the 6th line of the passage...
The structure of cycads male cones is quite consistent with the wind dispersal...
Answer is in the 12th line of the passage...
Furthermore, the structure of most female cycad cones seems inconsistent...
Correct Ans:(E)The structure of male cycad cones is consistent....

Qn:3)in favor of insect pollination of cycads presented in lines 2-4 would be more convincing if which..
Line:1 ... insects can function as pollinators of cycads...
Furthermore, cycads removed from native habitats ( therefore from insects) ..are usually infertile...
(A) Only a small variety of cycad species can be successfully transplanted. -> Wrong, because it speaks about small varities of cycads
(B) Cycads can sometimes be pollinated by means other than wind or insects. -> Wrong, because cycads removed from native habitats are usually infertile
(C) Insects indigenous to regions to which cycads are transplanted sometimes feed on cycads.-> Wrong, if insects eats cycads, their fertilization will be affected
(D) Winds in the areas to which cycads are usually transplanted are similar to winds in cycads’ native habitats.-> Wrong, if Ans D is true,
we won't be able to distinguish whether fertilization happens through wind or insects
(E) The transplantation of cycads from one region to another usually involves the accidental removal and introduction of insects as well.->Correct Ans:(E) Because, All other Answers are definitely wrong...

Qn:4)following is true of scientific investigations of cycad pollination?
(A) They have not yet produced any systematic evidence of wind pollination in cycads. -> Wrong,In Para Line No 9, Male sheds sheds almost 100 cubic centimeters of pollen, which is probably dispersed by wind...
(B) They have so far confirmed anecdotal reports concerning the wind pollination of cycads.-> Wrong,In Para Line No 5, anecdotal reports of wind pollination in cycads cannot be ignored.
(C) They have, until recently, produced little evidence in favor of insect pollination in cycads.-> Wrong,In Para Line No 4,cycads removed from native habitats ( therefore from insects) ..are usually infertile...
(D) They have primarily been carried out using cycads transplanted from their native habitats.-> Correct, Furthermore, cycads removed from their native habitats became infertile..
(E) They have usually concentrated on describing the physical characteristics of the cycad reproductive system.-> Wrong , The structure of cycads male cones is quite consistent with the wind dispersal..

Hi Expert,

Hope you are doing well in this hard time.

Request you to please provide the official explanation of all the questions as I picked wrong answer choices for all of the questions.

I'm new to this site, but it's quite clear that the at least 2 of the 4 OAs are incorrect. Is this often the case with questions on this website?

The most obviously incorrect answer is the one offered for Question 1.

(C) The degree to which the ovules of female cycads are accessible to airborne pollen. This is the OA, and yet it's the least sensical of all the answers.

The correct answer is E. Please change the answer to reflect this.


Edit: Also, the answer for Q3 is D: Winds in the areas to which cycads are usually transplanted are similar to winds in cycads’ native habitats.. This is the only answer that strengthens the fact that thew relationship between insect presence and pollination is causal. The passage states that it's the lack of insects in the new location that causes the sterility. There could be some other factor - such as change in wind - that is actually causing the difference. D eliminates this as a possibility.

Welcome to GMAT CLUB!

You are 100% spot-on as all of the answers added were wrong, I have updated the same and now they are good, The OAs are EEDA.

Thank you

No problem, Sajjad!

I was pretty shocked when my answers (EEDA) were all incorrect :D. Especially because I thought the passage was rather easy, and I was super-confident about my choices

Glad to see I wasn't overconfident!

Hello there please explain the question 4.

Posted from my mobile device

Explanation

4. The passage suggests that which of the following is true of scientific investigations of cycad pollination?

Difficulty Level: 750

Explanation

(A) They have not yet produced any systematic evidence of wind pollination in cycads.
This statement is correct because the passage mentions that there have been anecdotal reports of wind pollination in cycads but also that these reports cannot be ignored. The passage does not mention systematic evidence supporting wind pollination, indicating that such systematic evidence has not been produced.

(B) They have so far confirmed anecdotal reports concerning the wind pollination of cycads.
This statement is not supported by the passage. While the passage mentions anecdotal reports of wind pollination, it also suggests that these reports cannot be ignored. There is no confirmation or systematic evidence presented in the passage regarding wind pollination.

(C) They have, until recently, produced little evidence in favor of insect pollination in cycads.
Similar to (B) not supported by the passage.

(D) They have primarily been carried out using cycads transplanted from their native habitats.
The passage does not provide information about the methods or locations of scientific investigations of cycad pollination. There is no mention of whether these investigations primarily use transplanted cycads from their native habitats.

(E) They have usually concentrated on describing the physical characteristics of the cycad reproductive system.
The passage does discuss the physical characteristics of the cycad reproductive system, such as the structure of male and female cones and the release of pollen. However, it also discusses the role of insects and wind in pollination, so it doesn't suggest that scientific investigations have solely concentrated on describing the physical characteristics.
