The quality of heliotropism, a plant's ability to change its bearing to face the direction of the sun, is common in sunflowers. Moss displays the tendency to grow only on the side of trees opposite the most sunny direction. Therefore, moss exhibits the opposite phenomenon of heliotropism, which may be called contra-heliotropism.

The argument is flawed primarily because the author

A. does not take into consideration the fact that the direction of the sun changes during the day and between the southern and northern hemispheres
B. includes sunflowers and moss in the same group while ignoring obvious differences between them
C. creates a new word in Latin which does not really exist
D. fails to distinguish between a plant's special ability and a plant's special growth conditions
E. compares two types of plants which rarely grow in similar conditions

IMO D.

reason: heliotropism, a plant's ability should not be compared to moss' growth condition. To elaborate, we have no idea about the growth condition of sunflowers, which may be similar to that of moss. Alternatively, moss may also show heliotropism under some situations. Thus D seems reasonable to me.

(This applies to both plants and is universal. Does not explain)

B. includes sunflowers and moss in the same group while ignoring obvious differences between them
ability of sunflowers and growing tendency of moss are mentioned together. Difference between them does not matter.

C. creates a new word in Latin which does not really exist
Out of scope

D. fails to distinguish between a plant's special ability and a plant's special growth conditions
(ability of sunflowers and growing tendency of moss are mentioned together and growing tendency indicates growth conditions.)

E. compares two types of plants which rarely grow in similar conditions
(We have no such info mentioned above.)

this question shows why I do not like gmat from the economist at all. Certainly, the gmat prep has many great websites. They also have questions that does not sound as good as LSAT questions.

Nevertheless, if such questions from the gmat economist are modified and edited, then those questions may be used by the actual exam.
