Critical Reasoning

@David, Brian, Ashley: Can we please Have more Challenges??? Just four of them are posted

OA is C.

Great explanations above. No need to really add to what has been said by everyone.

You guys made quick work of this one.

Winners will be contacted by PM soon!

a always - extreme usage. POE.
b only - extreme word and other than plants its not mentioned in the argument. POE.
C derived using fact test.
D classic comparison of options in premises.POE.
E not mentioned in the argument. POE.

C is clear.

Haha..The contest isn't over yet. Still, 3.5 hours left.

True! There are a couple of more questions to come.

Contest ends noon Pacific Time - I think that is 7PM GMT.

You mean you are going to post 2 more questions today , that is the 1st day of the contest .
and then again other questions on the 2nd day of the contest .

Senescence in plants refers to the dying back of a portion of the plant usually in response to external factors. Leaves changing colors in the autumn and falling from the trees is an example of planned or programmed senescence, in this case in response to changes in the photo-period or length of daily sunlight. Annual plants that die back in the winter and return in the spring also display programmed senescence. Unplanned senescence occurs as a result of external factors as well. For example, under watering a houseplant can cause the plant to die back in an attempt to survive the drought conditions. Curiously, overwatering can cause a similar response as the excess moisture in the soil prevents plant roots from breathing.

Which of the following conclusions is most supported by the statements above?

A) Programmed senescence always occurs as the result of changes in the photo-period.
Too Extreme
It doesnt take into consideration the senescence taking place due to change of seasons or change in water supply
B) Senescence is a process that only occurs in plants.
The stimulus discusses only senescence in plants . too extreme . Stimulus doesnt provide enough info . that you could come to this conclusion
C) Both planned and unplanned senescence can occur due to changes in the external environment.
The stimulus gives enough examples that you can infer this.Correct
D) It is safer to underwater a plant rather than to overwater it.
No comparison between underwatering and over watering
E) There are some plants species that do not experience senescence.
The stimlus doesnt say this so you cant infer this

Just keep a sharp eye out for more questions from me within the nest three hours!

A) Programmed senescence always occurs as the result of changes in the photo-period.
INCORRECT : It is too extreme. We know from the stimulus that programmed senescence also includes plants that die in winter and return in spring, a condition as a result of something other than the changes in the photo-period

B) Senescence is a process that only occurs in plants.
INCORRECT : The stimulus primarily discusses senescence in plants. Nothing about the indication of senescence in species other than plants was ever mentioned. Thus, this answer choice is out of scope.

C) Both planned and unplanned senescence can occur due to changes in the external environment.
CORRECT : This is a paraphrase from the passage as the stimulus mentions that senescence occurs as a response to external factors and that senescence can be both planned and unplanned, also a result of external factors.

D) It is safer to underwater a plant rather than to overwater it.
INCORRECT : This is somehow against what was stated in the stimulus as it was said that overwatering can produce similar result to underwatering. As a result, which one is safer can hardly be implied.

E) There are some plants species that do not experience senescence.
INCORRECT : This inference could be true as opposed to must be true as the stimulus only discusses the phenomenon of senescence in plants. We don't know whether there are some plants that do not experience senescence.

+1 for C. not a good question though

Mirantdon -

Too straightforward for you?

Thanks David for the CR as well as a chance to win the great VP Books . @ MirantDon A question doesn't have to be Super LSAT 20-25 Level question to be good on the GMAT
