22. It can be inferred from the passage that gypsy moth caterpillars become immune to the wilt virus as a result of
consuming a wide range of nutrients from a variety of leaf types
feeding on leaves that contain high levels of phenols
producing fewer offspring, which favors the survival of the hardiest individuals
ingesting the virus together with leaves that do not contain tannin
growing population density, which outstrips the ability of the virus to multiply and spread
23. Which of the following statements about gypsy moth caterpillars is supported by information presented in the passage?
Wilt disease is more likely to strike small gypsy moth caterpillars than large ones.
The concentration of phenols in tree leaves increases as the gypsy moth caterpillar population dies off.
Female gypsy moth caterpillars stop growing after they ingest leaves containing phenols.
Differing concentrations of phenols in leaves have differing effects on the ability of the wilt virus to kill gypsy moth caterpillars.
The longer a gypsy moth population is exposed to wilt disease, the greater the likelihood that the gypsy moth caterpillars will become immune to the virus.
The sweep of narrative in A. N. Wilsons biography of C. S. Lewis is impressive and there is much that is acute and well argued. But much in this work is careless and unworthy of its author. Wilson, a novelist and an accomplished biographer, has failed to do what any writer on such a subject as Lewis ought to do, namely work out a coherent view of how the various literary works by the subject are to be described and commented on. Decisions have to be made on what to look at in detail and what to pass by with just a mention. Wilson has not thought this problem out. For instance, Till We Have Faces, Lewis treatment of the Eros and Psyche story and one of his best-executed and most moving works, is merely mentioned by Wilson, though it illuminates Lewis spiritual development, whereas Lewis minor work Pilgrims Regress is looked at in considerable detail.
