Directions: Answer the questions based on following reading passage.
The average temperature of the lobster-rich waters off the coast of Foerkland has been increasing for some years. In warmer water, lobsters grow faster. In particular, lobster larvae take less time to reach the size at which they are no longer vulnerable to predation by young cod, the chief threat to their survival. Consequently, the survival rate of lobster larvae must be going up, and the lobster population in Foerkland’s coastal waters is bound to increase.
Q. Which of the following, if true, most seriously weakens the argument?
  • a)
    There are indications that in recent years the fishing fleet operating off the coast of Foerkland has been taking cod at an unsustainably high rate.
  • b)
    The increase in water temperatures off Foerkland has not been as pronounced as the increase in average soil temperatures in Foerkland.
  • c)
    Because of their speeded-up growth, lobsters now get large enough to be legal catch before they reach reproductive maturity.
  • d)
    Even though lobsters grow faster in warmer waters, warmer waters have no effect on the maximum size to which a lobster can eventually grow.
  • e)
    Cod are a cold-water species, and the increasing water temperatures have caused a northward shift in Foerkland’s cod population.
Correct answer is option 'C'. Can you explain this answer?

Directions: Answer the questions based on following reading passage.T...
The argument in the passage concludes that the survival rate of lobster larvae is increasing and that the lobster population will increase. The basis for the conclusion is that the change in the water temperature, by speeding the growth of lobster larvae, has made them less vulnerable to predation by cod. However, Choice C points to a way that the faster growth of individual lobsters could create a threat to the population: lobsters that have not yet reproduced might be large enough to be legally caught. Thus, Choice C weakens the argument and is the correct answer.
Among the other choices, Choice A tends, if anything, to support the passage’s conclusion, by suggesting further reduction in the risks of predation by cod. The other choices have no clear bearing on the argument.

Evidence that weakens the argument:




Reproductive maturity and legal catch:
- If lobsters are reaching legal catch size before reaching reproductive maturity, it indicates that they are being caught before they have a chance to contribute to the population.
- This means that the increase in lobster population may not be as significant as expected, as many lobsters are being removed from the population before they can reproduce.

Directions: After reading the passage, read and respond to the questions that follow by selecting the best choice for each one.[1] An atmospheric gas that absorbs and emits thermal radiation in the infrared range is known as a greenhouse gas. [2] Without such gases, the surface temperature of the earth would have been a frigid -18°C instead of the current 15°C. [3] Many climate scientists claim that human activities since the beginning of the Industrial Revolution have led to a steady increase in the atmospheric concentration of many greenhouse gases, with a consequent increase in the planet's surface temperature by about 0.85°C in the last 130 years. [4] However, in order to correctly estimate the anthropogenic changes in earth's surface temperature, it is important to quantify the effect of external natural factors like large volcanic eruptions on the planet's surface temperature.[5] Though volcanic eruptions emit carbon dioxide, a greenhouse gas, the atmospheric concentration of this gas is about 16000 times the amount released by volcanic eruptions; therefore, no matter how large a volcanic eruption is, it cannot produce a significant change in the atmospheric carbon dioxide levels. [6] Further, the total amount of carbon dioxide emitted per year by volcanic eruptions – between 130 and 230 million tons – is roughly equivalent to that emitted in only three to five days of human activity.[7] It is mainly through the emission of sulfur dioxide gas and ash particles into the atmosphere that large volcanic eruptions affect earth's surface temperature. [8] Sulfur dioxide reacts with the water vapor present in air to form fine particles called sulfate aerosols. [9] Winds spread the cloud of aerosols and ash particles around the globe in weeks. [10] These particles absorb incoming solar radiation and scatter it back into space, thereby producing a cooling effect on the earth. [11] They take several years to settle out of the atmosphere and thus impact the global surface temperature for many years. [12] Robock and Mao have shown that for two years after a great volcanic eruption, the surface temperature decreases by 0.1 – 0.2°C. [13] The 1991 Pinatubo eruption in Indonesia was one of the largest volcanic eruptions in the twentieth century and resulted in a global surface cooling of 0.5°C for about two to four years after the eruption.[14] The El Chichón eruption in 1982 was the first major eruption whose climatic impact was studied in detail by modern instruments. [15] Though the emission volume of this eruption was similar to the Mount St. Helens eruption in 1980, El Chichón released seven times the amount of sulfate aerosols released by Mount St. Helens and lowered the earth's temperature by about 0.4°C as against a decrease of only 0.1°C for Mount St. Helens.Q. Which of the following statements, if true, will best support the assertion that a large volcanic eruption does not contribute to warming of the earth's surface?
