BioHome is a small research facility that supports a single person in a fully functional habitat. However, despite the stunning degree of effort to recreate a microcosm of the real world, engineers and scientists were surprised to discover that plants and other organic matter failed to grow in the same way they do in the regular atmosphere.
Which of the following, if true, best explains the surprising result described above?
(A) To be suitable for organic matter such as plants, fungi, and bacteria, oxygen must be within a very specific range, and BioHome’s oxygen was well beyond that which can be reasonably expected to support these life forms.
(B) Most of the plants housed in BioHome were from lower latitudes similar to the latitude of BioHome itself.
(C) Even though BioHome was engineered to sustain a single person, theoretically several people could fit within it.
(D) Nearly all materials used to construct the BioHome are cutting edge materials conducive to organic lifeforms.
(E) BioHome has subsequently become home to a number of plant species ranging from typical houseplants to more exotic tropical plants.

Given in the argument-
1. BioHome supports a single person in a fully-functional habitat
2. A lot of effort was put to recreate a microcosm of real world
3. Despite the efforts, plants and organic matter failed to grow in the same way they do in the regular atmosphere
What does the question stem ask?
Despite the efforts, why did plants and other organic matter fail to grow?
Approach-
1. Identify what was expected - for the plants and organic matter to grow as they do in the regular environment (let's just call it "to grow" for the sake of simplicity)
2. Identify why it was expected - because BioHome is a recreation of real world
3. Identify why it could possibly not be successful - BioHome missed something that we have in the regular environment and that helps plants and organic matter to grow
(A) To be suitable for organic matter such as plants, fungi, and bacteria, oxygen must be within a very specific range, and BioHome’s oxygen was well beyond that which can be reasonably expected to support these life forms. - sounds reasonable! If the appropriate amount of oxygen was missing, plants and other organic matter did not have what it takes to grow
(B) Most of the plants housed in BioHome were from lower latitudes similar to the latitude of BioHome itself. - This means that the geography of plants in their regular environment and in BioHome was the same. All this answer choice suggests is that geography is not the reason for plants to not grow. We are looking for something that resulted in plants and organic matter not growing. Therefore, this does not add any additional relevant information.
(C) Even though BioHome was engineered to sustain a single person, theoretically several people could fit within it. - We are not concerned about the number of people BioHome could sustain. The question asks us why plants and organic matter could not sustain
(D) Nearly all materials used to construct the BioHome are cutting edge materials conducive to organic lifeforms. - "conducive" means "favourable". Therefore, this answer choice suggests that nearly all the materials used for the construction of BioHome favoured the growth of organic forms. Great! But all that this answer choice suggests is that the materials used to construct the BioHome are not the reason for plants and organic matter to not grow. We are looking for something that resulted in plants and organic matter not growing. Therefore, this does not add any additional relevant information.
(E) BioHome has subsequently become home to a number of plant species ranging from typical houseplants to more exotic tropical plants. - This does not provide a reason. It just provides a fact that is not relevant to answer our question
