- Read the excerpt below and answer the questions that follow.(Solved)
Read the excerpt below and answer the questions that follow.
'No Joseph,'she said in an infantile whimper. "I can't bear that we can’t express the love that we have for one another because of some primitive culture. If by loving you, I offend the sensibilities of Nasila then let me offend and face the consequences of doing so!"
"I also love you very much," Joseph Parmuat responded finally. "I loved you the moment I saw you during your father’s homecoming ceremony. But then the clan matter came to separate us. It is true we have no blood relation. But Nasila culture dictates who are related and who are not. We are slotted among those who cannot marry."
"No, it can’t be, I cannot accept its verdict,” she said petulantly her words agonized. "No way, never!" She stopped, confused and angry with herself at her inarticulate outburst. She took several long steadying breaths and then said, "I cannot accept that a culture that does not feed,clothe or house me comes to control my life. Our lives belong to us, Joseph. The destiny of our lives is in our own hands. We should guard it jealously."At last they drew a little a part .His eyes were open, honest and steady upon her face.

- Read the following comprehension and answer the questions that follow.(Solved)
Read the following comprehension and answer the questions that follow.
Over the years man has cultivated to exhaustion the better soils in the plains. This has led to
progressive destruction of land to the point where some of the steeper hill slopes are cultivated so
that widespread erosion has been initiated. Meanwhile, the livestock are continuously being forced on to smaller areas of poorer land and further up the hill slopes where they have to compete with foresters. As a result the quantities of animal proteins, so necessary to human health, have steadily declined. Surprisingly, instead of accepting the responsibility for all his destruction, man blames livestock and in particular the goat.
Man has repeatedly failed to do anything to restore the fertility of the soils he has ravaged. After the last miserable crop has been harvested the land has been left to weeds. No attempt has been made to plant grass or to under plant the last agricultural crop with fodder species. Had this been done rehabilitation would have been quicker and sure and erosion would have been reduced. Thus the gradually worsening situation would be arrested.
If man would shoulder the responsibility for his own greedy misuse of the land, the goat could easily carry the blame for its own much smaller share in this degradation. Unfortunately, because human nature is what it is, man will find something to blame for his won carelessness. The goat has been chosen to carry this blame largely because it is often the last animal to be seen wresting a precarious living from the areas where man has done his worst and from which cattle and sheep have long since been forced to move.
Conservation of land depends on proper planning. Livestock numbers therefore, irrespective of species, should be strictly limited to a density which will permit pasture renewal instead of causing its degeneration. This adjustment of numbers should help man to have a balanced mixture of livestock.
Many writers in recent years have tried to show that there has been considerable improvement in mountain grazing areas after the banishment of the goat. Most, however, fail to indicate to what extent this has been due solely to the removal of the goat or to a reduction in other livestock densities or other measures such as erosion control, terracing, the building of gabions and grass plan planting. It is essential to ensure that results which are obtained in one environment are not automatically applied to different one. (Adapted from observation on the goat)
(a) According to paragraph one of the passage, who has man used as a scapegoat?
(b) In paragraph two, what two words show that land has not been very productive.
(c) Why has the quantities of animal proteins necessary to human health declined?
(d) Rewrite the following sentences according to instructions given.
(i) Unfortunately, because human nature is what it is, man will find something to blame for his own carelessness.
(Begin: The author stated that ......)
(ii) Thus, the gradually worsening situation would be arrested.
(Add a question tag).
(e) What could have been done to ensure quicker rehabilitation and reduce erosion.
(f) What other words could be used in place of those given without changing the meaning.
(i) Initiated
(ii) Miserable
(iii) Degradation
(iv) Banishment
(g) Rewrite in the active voice.
(i) The goat has been chosen for this blame.
(ii) Livestock are continually being forced onto poorer areas.
(h) How would you sum up the author’s argument in 1 or 2 sentences?
