An experiment conducted aboard Space Lab in 1983 was the first attempt

Question

An experiment conducted aboard Space Lab in 1983 was the first attempt to grow protein crystals in the low-gravity environment of space. That experiment is still cited as evidence that growing crystals in microgravity can increase crystal size: the authors reported that they grew lysozyme protein crystals 1,000 times larger than crystals grown in the same device on Earth. Unfortunately, the authors did not point out that their crystals were no larger than the average crystal grown using other, more standard techniques in an Earth laboratory.

No research has yet produced results that could justify the enormous costs of producing crystals on a large scale in space. To get an unbiased view of the usefulness of microgravity crystal growth, crystals grown in space must be compared with the best crystals that have been grown with standard techniques on Earth. Given the great expense of conducting such experiments with proper controls, and the limited promise of experiments performed thus far, it is questionable whether further experiments in this area should even be conducted.

The answer to question 4 seems incorrect, it should be "B", no? The fact that the author points out that the report failed to say that the crystals grown in the space lab tended to be the same size as those grown by different means on earth would point to "misleading"...

1. According to the passage, which of the following is true about the Space Lab experiment conducted in 1983? Here the author is asking which of the following statements is true about the space lab experiment conducted in 1983..... (A) It was the first experiment to take place in the microgravity environment of space. we dont know if this is the first experiment in space environment. Passage mentions first attempt to grow protein crystals in the low-gravity environment of space. (B) It was the first experiment in which researchers in space were able to grow lysozyme protein crystals greater in size than those grown on Earth. This choice says this was the first time the researchers were able to grow protein in space and have failed other times when the experiment was carried out... (C) Its results have been superseded by subsequent research in the field of microgravity protein crystal growth. The second paragraph last line says no further experiment in this was carried out. (D) Its results are still considered by some to be evidence for the advantages of microgravity protein crystal growth. Line 2 in passage "That experiment is still cited as evidence that growing crystals in microgravity" exactly implies this. (E) Its results are considered by many to be invalid because nonstandard techniques were employed. Not mentioned in passage that results were considered invalid. Hope this explains....

TheMechanic · Answer

I got thrown off by the word "Advantage" in option D. The passage does not indicate any kinda advantage from the experiment. The passage though indicates that evidences from the experiment are used to decide whether such experiments are practical or not.

But I did get lured to option B and ended up selecting it. I guess option D is best among the worst.

mehtakaustubh · Answer

The passage Line 2 says "growing crystals in microgravity can increase crystal size......grew lysozyme protein crystals 1,000 times larger than crystals grown in the same device on Earth" which is a advantage of microgravity.

I am not getting logic to question 4. can anyone explain?

mehtakaustubh · Answer

Para 1 Line 2 states: growing crystals in microgravity can increase crystal size: the authors reported that they grew lysozyme protein crystals 1,000 times larger than crystals grown in the same device on Earth.
Para1 line 3 states: the authors of exp did not point out that their crystals were no larger than the average crystal grown using other, more standard techniques in an Earth laboratory
Para2 line 2 states:To get an unbiased view of the usefulness of microgravity crystal growth, crystals grown in space must be compared with the best crystals that have been grown with standard techniques on Earth.

now lets analyze the choices considering the above three points:
(A)  Although the results of the experiment are impressive, the experiment was too limited in scope to allow for definitive conclusions.   This is the correct one... 
(B) The results of the experiment are impressive on the surface but the report is misleading. Refering to Para1 line 3 we can say results were drawn without comparing the output of other methods(limited scope) that does not mean the report is misleading... 
(C) The results of the experiment convincingly confirm what researchers have long suspected. It is not mentioned in passage what researchers suspected b4 the experiment 
(D) Because of design flaws, the experiment did not yield any results relevant to the issue under investigation. No design flaws are discussed in experiment. 
(E) The results of the experiment are too contradictory to allow for easy interpretation. Its never mentioned that the results of exp are contradictory

For question 1; Is B not the only objectively right answer? The passage states this

"was the first attempt to grow protein crystals in the low-gravity environment of space."
And the follow up sentence states "the authors reported that they grew lysozyme protein crystals 1,000 times larger than crystals grown in the same device on Earth."

(B) It was the first experiment in which researchers in space were able to grow lysozyme protein crystals greater in size than those grown on Earth.

1. This was the first experiment that grew protein crystals in space
2. The results of this experiment showed that the crystals grew larger in space than through the same device on earth.
Therefore it has to be the "First" experiment that showed that protein crystals grew bigger in space than on earth.

(D) Its results are still considered by some to be evidence for the advantages of microgravity protein crystal growth.

The stated correct answer (D) is speculative, no part of the passage mentions that "some" use this as advantages of microgravity protein growth." It can't be true because we'd have to speculate that there are people that speculate this, or that its an advantage to grow them in space. The study only states that under 1 particular, implied non-standard technique to grow crystals, that protein crystals in space outgrew those on earth. Nothing about what some people "consider" or that growing them in space in advantageous is an opinion that people have.

If I'm missing something, or if I'm right but my logic for approaching this question falls short would love some advice.

"the authors did not point out that their crystals were no larger than the  average  crystal grown using other, more standard techniques in an Earth laboratory." B is wrong because the experiment did not yield crystals that greater in size, as a matter if fact it was no larger than the average crystal grown in Earth. It was only larger when they were made with a specific technique, that is with that specific technique you can grow larger crystals in space than in earth.

Can you please explain Q4? 
The reason I eliminated Answer A was because there weren't opinions of "impressive" mentioned in passage but all statement of facts, can you please clarify how the author found the results impressive?

can someone explain Q-3 c) vs e) ?  Sajjad1994   GMATNinja

iamjatinagrawal · Answer

In option E, " The experiments " covers a wide variety of experiments apart from the ones mentioned in the passage. We cannot tell if all of those experiments conducted with this device are conducted with proper controls and we don't even know if any other experiments are even conducted using this particular device apart from growing these protein crystals. So, there are a lot of assumptions for this answer choice.

This might feel like an answer a little but is clearly not and as the option C says:   Crystals grown in the device on Earth tend to be much smaller than crystals grown in it in space.

Which can be verified clearly from the lines " the authors reported that they grew lysozyme protein crystals 1,000 times larger than crystals grown in the same device on Earth ". Hence C is the answer and not E.

Hope this was helpful.

Question 4:

The word “unfortunately” signals the author’s disapproval. By saying that the authors "did not point out" this crucial comparison — that the space-grown crystals were actually no larger than average Earth-grown crystals using standard techniques — the author is implying that the report was misleading.

That aligns with answer choice (B) - "The results of the experiment are impressive on the surface but the report is misleading."
