Question 1

Direction: Read the following passage and answer the items that follow. Your answers to these items should be based on the passage only.
Passage

Ecological-research over the last quarter of the century has established the deleterious effects of habitat fragmentation due to mining, highways and such other intrusions on forests. When a large block of forests gets fragmented into smaller bits, the edges of all these bits come into contact with human activities resulting in the degradation of the entire forests. Continuity of forested landscapes and corridors gets disrupted affecting several extinction-prone species of wildlife. Habitat fragmentation, is therefore considered as the most serious threat to biodiversity conservation. Ad hoc grants of forest lands to mining companies coupled with rampant, illegal mining is aggravating this threat.
What is the central focus of this passage?

Passage

The law in many parts of the world increasingly restricts the discharge of agriculture slurry into watercourses. The simplest and often the most economically sound practice returns the material to the land as semisolid manure or as sprayed slurry. This dilutes its concentration in the environment to what might have occurred in a more primitive and sustainable type of agriculture and converts pollutant into fertilizer. Soil micro organisms decompose the organic components of sewage and slurry and most of the mineral nutrients become available to be absorbed again by the vegetation.

The excess input of nutrients, both nitrogen and phosphorus - based, from agriculture runoff (and human sewage) has caused many 'healthy' oligotrophic lakes (low nutrients concentrations, low plant productivity with abundant water weeds, and clear water) to change to eutrophic condition where high nutrients inputs lead to high phytoplankton productivity (sometimes dominated by bloom-forming toxic species). This makes the water turbid, eliminates large plants and, in the worst situation, leads to anoxia and fish kills, so called cultural eutrophication.

Thus, important ecosystem services are lost, including the provisioning service of wild-caught fish and the cultural services associated with recreation. The process of cultural eutrophication of lakes has been understood for some time. But only recently did scientists notice huge 'dead zones' in the oceans near river outlets, particularly those draining large catchment areas such as the Mississippi in North America and the Yangtze in China. The nutrients-enriched water flows through streams, rivers and lakes, and eventually to the estuary and ocean where the ecological impact may be huge, killing virtually all invertebrates and fish in areas up to 70,000 km2 in extent. More than 150 sea areas worldwide are now regularly starved of oxygen as a result of decomposition of algal blooms, fuelled particularly by nitrogen from agricultural runoff of fertilizers and sewage from large cities. Oceanic dead zones are typically associated with industrialized nations and usually lie off countries that subsidize their agriculture, encouraging farmers to increase productivity and use more fertilizer.
According to the passage, why should the discharge of agriculture slurry into watercourses be restricted?
1) Loosing nutrients in this way is not a good practice economically.
2) Watercourses do not contain the microorganisms that can decompose organic components of agriculture slurry.
3) The discharge may lead to the eutrophication of water bodies.

Question 18

Direction: Read the following passage and answer the items that follow. Your answers to these items should be based on the passage only.
Passage
A moral act must be our own act; must spring from our own will. If we act mechanically, there is no moral content in our act. Such action would be moral, If we think it proper to act like a machine and do so. For, in doing so, we use our discrimination. We should bear in mind the distinction between acting mechanically and acting intentionally. It may be moral of a king to pardon a culprit. But the messenger carrying out the order of pardon plays only a mechanical part in the king's moral act. But if the messenger were to carry out the king's order considering it to be his duty, his action would be a moral one. How can a man understand morality who does not use his own intelligence and power of thought, but lets himself be swept along like a log of wood by a current? Sometimes a man defies convention and acts on his own with a view to absolute good.
Which of the following statements best describe/describes the thought of the writer?
1) A moral act calls for using our discretion.
2) Man should react to a situation immediately.
3) Man must do his duty.
4) Man should be able to defy convention in order to be moral.
Select the correct answer from the codes given below:
