Unfortunately, the more industrialized we become, the farther away we move from direct contact with plants, and the less distinct our knowledge of botany grows. Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose, an apple, or an orchid. When our Neolithic ancestors, living in the Middle East about 10,000 years age, discovered that certain grasses could be harvested and their seeds planted for richer yields the next season, the first great step in a new association of plants and humans was taken. Grains were discovered and from them flowed the marvel of agriculture: cultivated crops. From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varie-ties that grew wild and the accumulated knowledge of tens of thousands of years of experience and intimacy with plants in the wild would begin to fade away.
It is assumed in the passage that early humans ______.
A.probably had extensive knowledge of plants
B.thought there was no need to cultivate crops
C.did not enjoy the study of botany
D.placed great importance on the ownership of property

Fishing typically does not require land ownership, and because it remains, in general, open to all, it is often the employer of last resort in the developing world--an occupation when there are no other options. Worldwide, about 200 million people depend on fishing for their livelihoods. Within Southeast Asia alone, more than five million people fish full-time. In northern Chile ,40 percent of the population lives off the ocean. In Newfoundland, most employment came from fishing or servicing that industry--until the collapse of the cod fisheries in the early 1990s left tens of thousands of people out of work.
Although debates over the conservation of natural resources are often cast as a conflict between jobs and the environment, the restoration of fish populations would in fact boost employment. Michael P. Sissenwine and Andrew A. Rosenberg of the U. S. National Marine Fisheries Service have estimated that if depleted species were allowed to rebuild to their long-term potential, their sustainable use would add about $ 8 billion to the U. S. gross domestic product--and provide some 300, 000 jobs. If fish populations were restored and properly managed, about 20 million metric tons could be added to the world's annual catch. But restoration of ecological balance ,fiscal profitability, and economic security will require a substantial reduction in the capacity of the commercial fishing industry so that wild population can recover.
The necessary reductions in fishing power need not come at the expense of jobs. Governments could increase employment and reduce the pressure on fish populations by directing subsidies away from highly mechanized ships. For each $1 million of investment, industrial-scale fishing operations require only one to five people ,whereas small-scale fisheries would employ between 60 and 3000. Industrial fishing itself threatens tens of millions of fishermen working on a small scale by depleting the fish on which they depend for subsistence.
The animal source which supplies the most protein for human being is ______.
A.beef
B.fish
C.pork
D.chicken
