Ecologists Jannus and Banks hypothesized that the Red Sea rift developed along the line of a suture (a splice in the Earth's crust) formed during the late Proterozoic era, and that significant observable differences in the composition of the upper layers of rocks deposited on either side of the suture give clues to the different natures of the underlying igneous rocks.
Other geologists argued that neither the upper rock layers nor the underlying, igneous rocks on the one side of the rift differ fundamentally from the corresponding layers on the other side. These geologists believe, therefore, that there is inadequate evidence to conclude that a suture underlies the rift.
In response, Jannus and Banks asserted that the upper rock layers on the two sides of the rift had not been shown to be of similar age, structure, or geo-chemical content. Furthermore they cited new evidence that the underlying igneous rocks on either side of the rift contain significantly different kinds of rare metals.

1. It can be inferred from the passage that the "Other geologists" (second paragraph) could be most likely to agree with which of the following statements?
A. Similar geological features along both sides of a possible suture imply the existence of that suture.
B. Sutures can be discovered only where they are not obscured by super-imposed ecological features.
C. The composition of igneous rocks permits prediction of the likelihood of a rift developing through them.
D. It is possible to date igneous rocks by carefully studying the different kinds of rare metals contained in them and by observing their similarity to the layer of rock that lies above them.
E. The existence of rock layers on one side of a rift that are similar in composition to rock layers on the other side suggests that no suture exists between the two sides.

1. It can be inferred from the passage that the "Other geologists" (second paragraph) could be most likely to agree with which of the following statements?
Let us examine the paragraph that talks about "other geologists". According to the passage, they have claimed that:
The upper rock layers as well as the underlying igneous rocks on both sides of the rift are fundamentally similar, therefore there is inadequate evidence to conclude the existence of a suture underlying the Red Sea rift. From this, we can gather that differences in the rock layers and underlying igneous rocks can be signs of a suture. Let us examine the answer options.
A. Similar geological features along both sides of a possible suture imply the existence of that suture. This is the opposite of what the "other geologists" have stated. Incorrect.
B. Sutures can be discovered only where they are not obscured by super-imposed ecological features. Given that differences in rock layers over the underlying igneous rocks can be used to identify sutures, this is not what the "other geologists" state. Incorrect.
C. The composition of igneous rocks permits prediction of the likelihood of a rift developing through them. This, on first glance, appears probable since the "other geologists" base their rejection of a suture on the supposed similarities of the igneous rocks. However, we are not told what feature of the igneous rocks' similarity has led to this conclusion - rather than composition (as stated in this option), it could also be other features such as age, structure etc. We can hold on to this option for now and continue looking for a more direct answer.
D. It is possible to date igneous rocks by carefully studying the different kinds of rare metals contained in them and by observing their similarity to the layer of rock that lies above them. There is nothing in the paragraph about dating of igneous rocks. Incorrect.
E. The existence of rock layers on one side of a rift that are similar in composition to rock layers on the other side suggests that no suture exists between the two sides. Correct. This matches perfectly with the information given in the passage about "other geologists".
Since (E) gives a more direct summary of the conclusions of the "other geologists", we can go ahead and reject option (C).
2. It can be inferred from the passage that Jannus and Banks have done which of the following?
A. Drawn detailed diagrams of the Red Sea rift. While Janus and Banks have studied the Red Sea rift and made detailed predictions, they would probably have made detailed diagrams as well. However, the passage gives no information regarding any drawings of the rift, and, theorectically speaking, we must treat this as a strictly "may be true" option. We can hold on to it for now, but this is unlikely to be the final answer.
B. Based their conclusions on the way in which sutures develop in the Earth crust. There is no mention of any process by which sutures develop. Incorrect.
C. Rejected other geologists’ objections to their hypothesis about the Red Sea rift. Correct. In paragraph 2, the "other geologists" have questioned the idea that the Red Sea rift developed along the line of a suture. In paragraph 3, we are shown Janus and Banks providing arguments against this opinion. Therefore, it can be inferred that that they "rejected" the other geologists' objections.
D. Suggested that the presence of other rare metals in rocks indicate an underlying suture. Janus and Banks suggested that a difference in metals present on either side of the rift indicates the presence of a suture. This option does not clarify the "other" mentioned - other than what? Incorrect.
E. Asserted that rifts usually occur along the lines of sutures No such argument is made by them in this passage. Incorrect.
3. According to the passage, Jannus and Banks have mentioned all of the following properties of rocks along the Red Sea rift EXCEPT
A. age of the upper layers of rocks Mentioned in the first sentence of the 3rd paragraph.
B. structure of the upper layers of rocks Mentioned in the first sentence of the 3rd paragraph.
C. geochemical content of the upper layers of rocks Mentioned in the first sentence of the 3rd paragraph.
D. metallic content of the underlying igneous rocks Mentioned in the second (which is the last sentence of the passage) sentence of the 3rd paragraph (which is the last sentence of the passage).
E. age of the underlying igneous rocks Correct. This is never mentioned by them in this passage.
Hope this helps.
