| Efforts to educate people about the
risks of substance abuse seem to deter some people from using dangerous
substances, if such efforts are realistic about what is genuinely dangerous and
what is not. Observed declines in the use of such drugs as LSD, PCP, and
Quaaludes since the early 1970s are probably related to increased awareness of
the risks of their use, and some of this awareness was the result of warnings

A.25-40mm (±5mm) B.30-40mm (±5mm) C.30-45mm (±5mm) D.33-43mm (±5mm) [简答题]Because agriculture is so important to a nation’s well-being, governments have always been concerned with it. For example, the United States and Canada have long produced surpluses that complicate their economies. Surpluses tend to lower prices to farmers and seriously endanger the agriculture industry. Governments have Instituted systems of price supports to maintain a fair price when surpluses cause prices to drop. The system in the United States is a good example. A government program supports the prices paid to farmers for grains, and other agricultural products.
Support prices are based on parity, which is the ratio between the prices farmers receive for their crops and the prices they must pay for things they need. The government selected the period from 1910 to 1914 as a time when farm prices were in a fair ratio with farming costs. This is the base period now used to determine parity prices.
