1). This three-dimensional image gives us depth perception. 2). The child then loses depth perception. 3). With normal vision, both eyes aim at the same spot, and the brain then fuses the two pictures into a single three-dimensional image. 4). In a young child who develops strabismus (a squint), the brain learns to ignore the image of the misaligned eye and sees only the image from the straight or better-seeing eye.
Answer: C 31 is a mandatory pair, 3 begins to explain how our eyes and brain are related in creating a single threedimensional image. 1 mentions that this threedimensional image gives us depth perception. 4 presents a situation where a child (with a squint) does not have this normal vision and the process of creating the three-dimensional image gets disturbed. 2 concludes the discussion by stating the result of this abnormal alignment of eyes.
Q. No. 140:
1). Because the Internet is a global network of computers each computer connected to the Internet must have a unique (internet) address. 2). However, if you connect to the Internet from a local area network (LAN) your computer might have a permanent IP address or it might obtain a temporary one from a DHCP (Dynamic Host Configuration Protocol) server. 3). Internet addresses are in the form nnn.nnn.nnn.nnn where nnn must be a number from 0-255, and this address is known as an IP address. 4). If you connect to the Internet through an Internet Service Provider (ISP), you are usually assigned a temporary IP address for the duration of your dial-in session.
Answer: C The key to this question lies in identifying the mandatory pairs: 13 and 42. 1 introduces the necessity of a unique (internet) address for each computer connected to the Internet, 3 specifies the form and definition of the IP address. 4 follows the flow of information on this. 2 follows 4, as we see usage of ‘however’ in the beginning of sentence 2 presenting a contrast- an obvious difference between the two ways to connect, described in 4 and 2. Thus, 1342 is the logical sequence.
Q. No. 141:
1). In the longer term, major glacier-fed rivers, it was feared, would run dry, affecting millions in the region. 2). The Intergovernmental Panel on Climate Change (IPCC) had said that Himalayan glaciers were receding faster than in any other part of the world. 3). This report sparked concerns that there could be increased flooding in the short term, as glacial lakes suddenly overflowed. 4). The panel observed: “If the present rate continues, the likelihood of them disappearing by 2035 and perhaps sooner is very high if the Earth keeps warming at the current rate.”
Answer: A 2 introduces the subject - state of glaciers in the Himalayas. 4 adds on by presenting the panel’s observation, ‘them’ in 4 denotes ‘Himalayan glaciers’ mentioned in 2. 3 mentions the possible consequences in the short term, and 1 mentions the possible consequences in the long term. Thus the logical sequence is 2431.
Q. No. 142:
1). So too it is impossible for there to be any propositions of ethics. Propositions can express nothing that is higher. 2). The sense of the world must lie outside the world. In the world everything is as it is, and everything happens as it does happen: in it no value exists - and if it did exist it would have no value. If there is any value that does have value, it must lie outside the whole sphere of what happens and is the case. For all that happens and is the case is accidental. What makes it non-accidental cannot lie within the world, since if it did it would itself be accidental. It must lie outside the world. 3). It is clear that ethics cannot be put into words. Ethics is transcendental. 4). All propositions are of equal value.
Answer: A It is clear that statement 4 may be the first statement as compared to statement 3 since statement 3 has a concluding essence to it by mentioning, “ethics cannot be put into words. Ethics is transcendental.” This would indicate that the paragraph is on “ethics” and statement 3 is effectively a summary of what is mentioned in the paragraph. Statement 2 continues after statement 4. The idea in the second statement does not match up with any of the other three statements directly. However, the idea of „value‟ is continued from statement 4 to statement 2. Hence, that is a pair. Statements 2-1 are also a pair since statement 1 begins with “So too...” continuing from the subject under discussion in statement 2. We have already established statement 3 as the concluding statement. Hence, the correct answer is option A.
Q. No. 143:
1). The fact all contribute only to setting the problem, not to its solution. 2). How things are in the world is a matter of complete indifference for what is higher. God does not reveal himself in the world. 3). To view the world sub specie aeterni is to view it as a whole- a limited whole. Feeling the world as a limited whole- it is this that is mystical. 4). It is not how things are in the world that is mystical, but that it exists.
Answer: B An easy question if you managed to locate the mandatory pair. The talk about „what is mystical‟ has been carried out in statements 3 and 4. Statement 4 stresses on “it is NOT how things are in the world that is mystical...” and statement 3 continues with “... it is this that is mystical.” An answer to what is not but what is. Thus, statement 3 follows statement 4 (4-3). This pair is there in only option C. For confirmation, we can check the sequence of 2-1-4. The higher thing is indifferent to things in the world in statement 2– they contribute to setting the problem in statement 1– how things are not mystical in statements 4 and 3. The sequence makes sense and maintains a logical flow.
Q. No. 144:
1). The operation is what has to be done to one proposition in order to make other out of it. 2). Structure of proposition stands in internal relations to one another. 3). In order to give prominence to these internal relations we can adopt the following mode of expression: we can represent a proposition as the result of an operation that produces it out of other propositions (which are bases of the operation). 4). An operation is the expression of a relation between the structures of its result and of its bases.
Answer: C The keywords “these internal relations” in statement 3 refers to “internal relations” mentioned in statement 2. Therefore, 3 follows 2 (2-3). With that we can eliminate options B and D. Statement 4 introduces the idea of „operations‟ (an operation), which is followed up with further discussions on the same in statements 3 and 1.
