Question 27-32:

27. ix (para B, line 2-7: ―‗older‘. Ageing in this case must occur according to the laws of
physical chemistry and of thermodynamics. Although the same law holds 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‖)

28. ii (para C, line 4-7: ―system to age and die. Nevertheless, a restricted life span, ageing,
and then death are basic characteristics of life. The reason for this is easy to
recognise: in nature, the existent organisms either adapt or are regularly replaced by
new types‖)

29. vii (para D, line 4-8: ―constant. For example, the average duration of human life has
hardly changed in thousands of years. Although more and more people attain an
advanced age as a result of developments in medical care and better nutrition, the
characteristic upper limit for most remains 80 years‖)

30. i (para E, first 3 lines: ―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‖)

31. viii (para F, line 5-10: ―captivity. Animals which save energy by hibernation or
lethargy (e.g. bats or hedgehogs) live much longer than those which are always active.
The metabolic rate of mice can be reduced by a very low consumption of food
(hunger diet). They then may live twice as long as their well fed comrades. Women
become distinctly (about 10 per cent) older than men‖)

32. iv (para G, first 2 lines: ―It follows from the above that sparing use of energy reserves
should tend to extend lite. Extreme high performance sports‖)

Question 33-36:
33. physical chemistry
34. thermodynamics
(para B, line 4-5: ―Ageing in this case must occur according to the laws of physical
chemistry and of thermodynamics. Although the‖)

35. adapt (para C, line 9-10: ―characteristics and in the course of their individual lives
they are tested for optimal or better adaptation to the environmental conditions‖)

36. Immortality (para C, last 3 lines: ―conditions. Immortality would disturb this system
— it needs room for new and better life. This is the basic problem of evolution‖)

Question 37-40:
37. NO (para D, last 4 lines: ―the simple wear and tear theory is the observation that the
time within which organisms age lies between a few days (even a few hours for
unicellular organisms) and several thousand years, as with mammoth trees.‖)

38. YES (para B, line 7-9: ―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‖)

39. NOT GIVEN

40. YES (para G, first 2 lines: ―It follows from the above that sparing use of energy
reserves should tend to extend lite. Extreme high performance sports‖)
