@Anusha-Ramjattan,

Could you clarify which question this is referring to? Is it example
1, 2, 3, 4, or another question? Let us know, and we'll be happy to
help!

HI Ravi,
Number 2
so sorry, its my first time posting and I need to get the hang of it. its question number two and for some reason I thought the first line was the authors conclusion.

@Anusha-Ramjattan,

Let's take a look.

This question is a bit tricky, as there aren't any large changes in
attitude to signify a conclusion. However, if you look closely, you'll
notice that all of the statements in the stimulus are descriptive
except for the one in the middle that says, "Research efforts now are
justified if there is even a chance of making another planet
inhabitable." The rest of the statements are all used to support this
claim, which tells us that it's the main conclusion of the argument.

The first sentence may seem like a conclusion at first, but once you
continue to read the rest of the stimulus, it's clear that there
aren't any other sentences that are directly supporting it. On the
other hand, the first sentence is used along with the others to
support that claim in the middle.

You probably picked (A), but as noted above, (A) is just a premise
that is supporting the claim that research is justified, so it's out.

(D) says, "research efforts aimed at discovering how to change the
climate of Mars are justified"

(D) looks great, and it matches our anticipation. This is a
restatement of the author's main point: the research efforts are
justified. This is the correct answer choice.

Does this make sense? Let us know if you have any other questions!
