[1] On the one hand, there are clear ethical arguments against animal experimentation. [2] A wide variety of animals is currently in use for laboratory tests, with the most common being mice or rats thanks to their short life span and high fertility rate. [3] To use a common example of this practice, laboratory mice may be given an illness so that the effectiveness of a new drug can be measured. [4] Opponents of such research argue that humans have no right to subject animals to this kind of trauma, and that the lives of all creatures should be respected. [5] In fact, animal right activists aren’t just the people you see holding up signs when you’re commuting to work in the morning, and they are certainly not violent protestors who burn down lab buildings with the animals inside.

 [6] They believe that the benefits to humans do not justify the suffering caused, and that scientists should use alternative methods of research. 

[7] On the other hand, reliable alternatives to animal experimentation may not always be available. [8] Supporters of the use of animals in medical research believe that a certain amount of suffering on the part of mice or rats can be justified if human lives are saved. [9] As can be seen from reality, through gnawing, nest-building, and defecation, both rats and mice can cause a great deal of damage to the structure of people’s homes as well as eating and contaminating their food. [10] They argue that opponents of such research might feel differently if a member of their own families needed a medical treatment that had been developed through the use of animal experimentation. [11] If the worst case scenario of death unfortunately happens, the bereavement period is associated with elevated risk for the onset of multiple psychiatric disorders, consistently across the life course and coincident with the experience. [12] Personally, I agree with the banning of animal testing for non-medical products, but I feel that it may be a necessary evil where new drugs and medical procedures are concerned.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 55 to 64.

The livelihood of each species in the vast and intricate assemblage of living things depends on the existences of other organisms. This interdependence is sometimes subtle, sometimes obvious. Perhaps the most straight forward dependence of one species on another occurs with parasites, organisms that live on or in other living things and derive nutrients directly from them. The parasitic way of life is widespread. A multitude of microorganisms (including viruses and bacteria) and an army of invertebrates - or creatures lacking a spinal column (including crustaceans, insects, and many different types of worms) - make their livings directly at the expense of other creatures. In the face of this onslaught, living things have evolved a variety of defense mechanisms for protecting their bodies from invasion by other organisms.

Certain fungi and even some kinds of bacteria secrete substances known as antibiotics into their external environment. These substances are capable of killing or inhibiting the growth of various kinds of bacteria that also occupy the area, thereby eliminating or reducing the competition for nutrients. The same principle is used in defense against invaders in other groups of organisms. For example, when attacked by disease - causing fungi or bacteria, many kinds of plants produce chemicals that help to ward off the invaders. Members of the animal kingdom have developed a variety of defense mechanisms for dealing with parasites.

Although these mechanisms vary considerably, all major groups of animals are capable of detecting and reacting to the presence of "foreign" cells. In fact, throughout the animal kingdom, from sponges to certain types of worms, shellfish, and all vertebrates (creatures possessing a spinal column), there is evidence that transplants of cells or fragments of tissues into an animal are accepted only if they come from genetically compatible or closely related individuals. The ability to distinguish between "self" and "nonself", while present in all animals, is most efficient among vertebrates, which have developed an immune system as their defense mechanism. The immune system recognizes and takes action against foreign invaders and transplanted tissues that are treated as foreign cells.

The word "intricate" in line 1 is closest in meaning to ________.

A. widespread 

B. difficult

C. complex

D. critical
