Homeostasis, an animal’s maintenance of certain internal variables within an acceptable range, particularly in extreme physical environments, has long interested biologists. The desert rat and the camel in the most water-deprived environments, and marine vertebrates in an all-water environment, encounter the same regulatory problem: maintaining adequate internal fluid balance.
For desert rats and camels, the problem is conservation of water in an environment where standing water is nonexistent, temperature is high, and humidity is low. Despite these handicaps, desert rats are able to maintain the osmotic pressure of their blood, as well as their total body-water content, at approximately the same levels as other rats. One countermeasure is behavioral: these rats stay in burrows during the hot part of the day, thus avoiding loss of fluid through panting or sweating, which are regulatory mechanisms for maintaining internal body temperature by evaporative cooling. Also, desert rats’ kidneys can excrete a urine having twice as high a salt content as sea water.
Camels, on the other hand, rely more on simple endurance. They cannot store water, and their reliance on an entirely unexceptional kidney results in a rate of water loss through renal function significantly higher than that of desert rats. As a result, camels must tolerate losses in body water of up to thirty percent of their body weight. Nevertheless, camels do rely on a special mechanism to keep water loss within a tolerable range: by seating and panting only when their body temperature exceeds that which would kill a human, they conserve internal water.
Marine vertebrates experience difficulty with their water balance because though there is no shortage of seawater to drink, they must drink a lot of it to maintain their internal fluid balance. But the excess salts from the seawater must be discharged somehow, and the kidneys of most marine vertebrates are unable to excrete a urine in which the salts are more concentrated than in seawater. Most of these animals have special salt-secreting organs outside the kidney that enable them to eliminate excess salt.
Which of the following statements is best described as an assertion of opinion rather than an assertion of fact?
  • a)
    There have been many proposals for a flat income tax.
  • b)
    The government has put forward a proposal to levy a flat income tax of 20% on elearning Indian citizens.
  • c)
    In the restaurant, alcohol is not served to patrons who are less than 20 years of age.
  • d)
    The search for the next president will start in the next 15 days.
Correct answer is option 'A'. Can you explain this answer?

CLAT Question

While a fact is anything that can be verified for its correctness, an opinion is a point of view. Option A is an assertion of opinion as it uses the word 'many' which is purely subjective, implying that what could be 'many' for a certain section of people may not be 'many' for some others. All other statements have statistics or figures that can be checked for correctness.
