As a result of the recent oil crisis, 9.9 million of California’s 15 million motorists were subjected to an odd – even plan of gas rationing. The governor signed a bill forcing motorists with license plates ending in odd numbers to buy gas only on odd – numbered days, and those ending in even numbers on even – numbered days. Those whose plates were all letters or specially printed had to follow the odd – numbered plan.
Exceptions were made only for emergencies and out – of – state – drivers. Those who could not get gas were forced to walk, bike, or skate to work.

Read the following passages and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the following questions
The biological community changes again as one moves from the city to the suburbs. Around all cities is a biome called the "suburban forest". The trees of this forest are species that are favored by man, and most of them have been deliberately planted. Mammals such as rabbits, skunks, and opossums have moved in from the surrounding countryside. Raccoons have become experts at opening garbage cans, and in some places even deer wander suburban thoroughfares. Several species of squirrel get along nicely in suburbia, but usually only one species is predominant in any given suburb -fox squirrels in one place, red squirrels in another, gray squirrels in a third - for reasons that are little understood. The diversity of birds in the suburbs is great, and in the South, lizards thrive in gardens and even houses. Of course, insects are always present. There is an odd biological sameness in these suburban communities. True, the palms of Los Angeles are missing from the suburbs of Boston, and there are species of insects in Miami not found in Seattle. But over wide stretches of the United States, ecological conditions in suburban biomes vary much less than do those of natural biome. And unlike the natural biomes, the urban and suburban communities exist in spite of, not because of, the climate
