Question 27: Paragraph B
Now, in lines 1-6 first, the writer talks about the ageing of ‘dead’ products/ objects and that of organisms, “Our ‘dead’ products are ‘static’, closed systems. It is always the basic material which constitutes the object and which, in the natural course of things, is worn down and becomes ‘older’. Ageing in this case must occur according to the laws for a living organism, the result of this law is not inexorable in
the same way. At least as long as a biological system has the ability to renew itself it could actually become older without ageing; .. .. .”
Therefore, it can be clearly understood that dead objects is worn down and becomes older; for a living
organism, becoming older can happen without ageing.
Answer: ix (Fundamental differences in ageing of objects and organisms)
Question 28: Paragraph C
Now, in the last few lines of paragraph C, “.. .. . Because of changes in the genetic material (mutations) these have new characteristics and in the course of their individual lives they are tested for optimal or better adaptation to the environmental conditions. Immortality would disturb this system – it needs room for new and better life.. … .”
The lines suggest that changes in genetic materials characterize them with new features and these new characteristics need to be tested so that organisms can adapt to the environment. If organisms don’t die, expectation of new and better life becomes impossible.
Answer: ii (Why dying is beneficial)
Question 29: Paragraph D
Now, in the first few lines, “Every organism has a life span which is highly characteristic. There are striking differences in life span between different species, but within one species the parameter is relatively constant.”
Here, constant = stable, but = despite,
Answer: vii (A stable life span despite improvements)
Question 30: Paragraph E
Now, in paragraph E, the first few lines provide us with the answer, “If a life span is a genetically determined biological characteristic, it is logically necessary to propose the existence of an internal clock, which in some way measures and controls the ageing process and which finally determines death as the last step in a fixed programme.”
This is the description of the biological clock.
Answer: i (The biological clock)
Question 31: Paragraph F
Paragraph F mainly deals with the effect of energy consumption by organisms and animals, “Animals which save energy… . .. .. live much longer than those which are always active”.
We find examples of what happens to different animals like crocodiles, tortoises and birds which do not use much energy. Then we find comparisons on women and men who use different levels of energy.
Answer: viii (Energy consumption)
Question 32: Paragraph G
Now, the first line of paragraph G gives us the answer, “It follows from the above that sparing use of energy reserves should tend to extend life.”
Here, extend = prolong,
Answer: iv (Prolonging your life)

Question 33 & 34:
Objects age in accordance with principles of 33. ________ and of 34. _________
Keywords: objects, age, principles of,
Now, in paragraph B, lines 3-4, the writer talks about the ageing of objects, “. . . Ageing in this case (case of objects) must occur according to the laws of physical chemistry and thermodynamics.”
Here, the laws = principles,
33. physical chemistry
Question 35: Through mutations, organisms can ________ better to the environment
Keywords: through mutations, organisms, better, environment,
Now, in paragraph C, lines 6-8, “Because of changes in the genetic material (which means mutations) these (which means organisms) have new characteristics and in the course of their individual lives they are tested for optimal or better adaptation to the environmental conditions”.
Here, for the question, we cannot write ‘adaptation’ as our answer. The question has a modal verb ‘can’ for which our answer had to be a main verb. The verb for ‘adaptation’ is ‘adapt’.
Question 36: ________ would pose a serious problem for the theory of evolution
Keywords: pose a serious problem, theory of evolution,
Now, in paragraph C, at the last line: “Immortality would disturb this system – it needs room for new and better life. This is the basic problem of evolution”.
Here, disturb this system = pose a serious problem,

Question 37: The wear and tear theory applies to both artificial objects and biological systems.
Keywords: wear and tear theory, artificial objects and biological systems,
Now, in paragraph A, lines 3-4, the writer talks about ‘the wear and tear theory’, “. . .. products which are subjected to natural wear and tear during use.” Then, in the end of this paragraph, the writer raises a big question on whether the theory applies to both living things and artificial objects, “. . .But are the wear and tear and loss of function of technical objects and the death of living organisms really similar or
Here, the raised question gives us the indication that the theory does not apply to both.
Question 38: In principle, it is possible for a biological system to become older without ageing.
Keywords: principle, possible, biological system, become older without ageing,
Now, in paragraph B, lines 6-7, “ . . . . At least as long as a biological system has the ability to renew itself it could actually become older without ageing; … ..”
The sentence is a clear match with the question.
Question 39: Within seven years, about 90 per cent of a human body is replaced as new.
Keywords: seven years, 90 per cent of human body, replaced as new,
Now, in this passage, we don’t find any reference to seven years or 90 percent.
Answer: NOT GIVEN
Question 40: Conserving energy may help to extend a human’s life.
Keywords: conserving energy, extend, life,
Now, in paragraph G, the very first lines give us the answer for this question, “It follows from the above that sparing use of energy reserves should tend to extend life.”
Here, conserving energy = sparing use of energy reserves,
The sentence is a clear match with the question.
