Hello Steinbeck,

Refer to the following lines from the passage:
"Both neurotoxins, while somewhat effective, interfere with the slugs' feeding behavior and limit their ingestion of the poison, increasing the probability that some will stop feeding before receiving a lethal dose."

The statement tells us that the neurotoxins may not be effective ,as some slugs will stop feeding before intake of a lethal dose.

The question talks on how to make neurotoxins more effective?
Pre-Thinking :Neurotoxins will be more effective if they impact the feeding behavior only after the slugs have received a lethal dose

Now Look at the answer choices:
[A] is not mentioned in the passage
[B] If the slugs ability to taste food is reduced then it will not take a lethal dose of neurotoxin so neurotoxins effectiveness will be reduces further.
[C] Makes Sense. This is the expected behavior.
[D] Same problem as option choice B. If neurotoxins reach the central pattern generator more quickly slugs may not intake a lethal dose. The effectiveness of the poison will be reduced farther.
[E] Passage does not mentions anything which will make neurotoxins more effective if they are accumulated only in the Central pattern generator

Passage-01 GMATPrep RCs-Collection(Main article)
Most farmers attempting to control slugs and snails turn to baited slug poison, or molluscicide, which usually consists of a bran pellet containing either methiocarb or metaldehyde. Both chemicals are neurotoxins that disrupt that part of the brain charged with making the mouth move in a coordinated fashion - the "central pattern generator" - as the slug feeds. Thus, both neurotoxins, while somewhat effective, interfere with the slugs' feeding behavior and limit their ingestion of the poison, increasing the probability that some will stop feeding before receiving a lethal dose. Moreover, slugs are not the only consumers of these poisons: methiocarb may be toxic to a variety of species, including varieties of worms, carabid beetles, and fish.

Researchers are experimenting with an alternative compound based on aluminum, which may solve these problems, but this may well have a limited future as we learn more about the hazards of aluminum in the environment. For example, some researchers suggest that acid rain kills trees by mobilizing aluminum in the soil, while others have noted that the human disease Alzheimer's is more prevalent in areas where levels of aluminum in the soil are high. With farmers losing as much as 20 percent of their crops to slugs and snails even after treatment with currently available molluscicides, there is consider able incentive for researchers to come up with better and environmentally safer solutions.
1. In the passage, the author is primarily concerned with
A. describing the limitations of molluscicides that affect feeding behavior
B. proposing alternatives to current methods of controlling slugs and snails
C. emphasizing the need for an alternative to currently available molluscicides conclusion in the 2nd para end .
D. explaining how molluscicides are used to control slugs and snails
E. criticizing the use of hazardous material for controlling slugs and snails

2. The author suggests that which of following is true of the "alternative compound" mentioned in the highlighted text?
A. It is more effective in destroying snails than in destroying slugs.
B. It begins to affect slugs' feeding behavior before they ingest a lethal dose.
C. It affects more species of fish than does metaldehyde.
D. It may not be environmentally safer than methiocarb. 2nd para is all about the -ve impacts of aluminium .
E. It may be less damaging to trees than metaldehyde.

3. The author cites which of the following as a disadvantage of methiocarb?
A. It contains high levels of aluminum.
B. It may react with acid rain to kill trees.
C. It has been associated with Alzheimer's disease.
D. It may be toxic to some species of fish. as per mentioned in 1st para
E. It may not be as effective in killing slugs as metaldehyde is. comparison wrong , not stated .

4.The passage suggests that methiocarb and metaldehyde would be more effective as slug poisons if it were true that they
A. disrupt the slug's digestive processes rather than its reproductive functions
B. reduce the slug's ability to taste food
C. begin to affect the feeding behavior of a slug only after it has ingested a lethal dose in 1st para , its stated that chemical impacts the feeding behavious thus slugs can't have leatheal intakes.
D. reach the central pattern generator more quickly
E. accumulate only in the central pattern generator rather than throughout the brain

Took 4 mins 20 seconds , including 2 mins to read the passage .
This is by far one of the easiest GMAT RC passage ever

-The author is not stating an opinion
- The author is discussing efforts that have been made to reduce slug population
-The author believes that there is more that can be done to ensure good control of slug population

1."With farmers losing as much as 20 percent of their crops to slugs and snails even after treatment with currently available molluscicides, there is considerable incentive for researchers to come up with better and environmentally safer solutions."

2.
"an alternative compound based on aluminum, which may solve these problems, but this may well have a limited future as we learn more about the hazards of aluminum in the environment."

3.
"methiocarb may be toxic to a variety of species, including varieties of worms, carabid beetles, and fish."

4.
"Thus, both neurotoxins, while somewhat effective, interfere with the slugs' feeding behavior and limit their ingestion of the poison, increasing the probability that some will stop feeding before receiving a lethal dose."

I am not able to understand why 1st question's answer is C but not E. because, according to passage the author is suggesting alternatives to both molluscicides and aluminum based product but C is specific to molluscicides. Also, The author is providing the hazardous effects of both mossuscicides and aluminum based products. And hence E is more appealing.

1. In the passage, the author is primarily concerned with
C. emphasizing the need for an alternative to currently available molluscicides
" there is consider able incentive for researchers to come up with better and environmentally safer solutions"
D. explaining how molluscicides are used to control slugs and snails
In the 1st paragraph author shows how molluscicides are used to control slugs and snails. In that author also writes about the negative impact that mollusciscides have. In the next paragraph, author talks about an alternative compund and the probable negative impact the alternative compund has.
E. criticizing the use of hazardous material for controlling slugs and snails
Author is not criticizing. He is citing the negative impact mollusciscides have and why alternative to mollusciscides is required : 1. farmers are losing as much as 20 percent of their crops to slugs and snails even after treatment with currently available molluscicides and 2. Mollusciscides have negative impact

Took around 8 minutes to solve the question - missed the last question, as I missed the complete meaning of the sentence - "Thus, both neurotoxins, while somewhat effective, interfere with the slugs' feeding behavior and limit their ingestion of the poison, increasing the probability that some will stop feeding before receiving a lethal dose." in a haste.
Takeaway -> understand each line well before solving the questions.
