Beads were probably the first durable
ornaments humans possessed, and the intimate relationship they had with their
owners is reflected in the fact that beads are among the most common items found
in ancient archaeological sites. In the past, as today, men, women, and children
adorned themselves with beads. In some cultures still, certain beads are often
worn from birth until death, and then are buried with their owners for the
afterlife. Abrasion due to daily wear alters the surface features of beads, and
if they are buried for long, the effects of corrosion can further change their
appearance. Thus, interest is imparted to the bead both by use and the effects
of time.
Besides their wearability, either as jewelry or
incorporated into articles of attire, beads possess the desirable
characteristics of every collectible. The

Federal efforts to aid minority
businesses began in the 1960’s when the Small Business Administration (SBA)
began making federally guaranteed loans and government-sponsored management and
technical assistance available to minority business enterprises. While this
program enabled many minority entrepreneurs to form new businesses, the results
were disappointing, since managerial inexperience, unfavorable locations, and
capital shortages led to high failure rates. Even 15 years ’after the program
was implemented, minority business receipts were not quite two percent of the
national economy’s total receipts.
Recently federal policymakers
have adopted an approach intended to accelerate development of the minority
business sector by moving away from directly aiding small minority enterprises
and towar
A. It provided enough loans to minority enterprises.

[不定项选择题]The U.S. Postal Service (USPS) continues to bleed red ink. It reported a net loss of $5.6 billion for fiscal 2016, the 10th straight year its expenses have exceeded revenue. Meanwhile, it has more than $120 billion in unfunded liabilities, mostly for employee health and retirement costs. There are many bankruptcies. Fundamentally, the USPS is in a historic squeeze between technological change that has permanently decreased demand for its bread-and-butter product, first-class mail, and a regulatory structure that denies management the flexibility to adjust its operations to the new reality
And interest groups ranging from postal unions to greeting-card makers exert self-interested pressure on the USPS’s ultimate overseer-Congress-insisting that whatever else happens to the Postal Service, aspects of the status quo they depend on get protected. This is why repeated attempts at reform legislation have failed in recent years, leaving the Postal Service unable to pay its bills except by deferring vital modernization.
Now comes word that everyone involved---Democrats, Republicans, the Postal Service, the unions and the system’s heaviest users—has finally agreed on a plan to fix the system. Legislation is moving through the House that would save USPS an estimated $28.6 billion over five years, which could help pay for new vehicles, among other survival measures. Most of the money would come from a penny-per-letter permanent rate increase and from shifting postal retirees into Medicare. The latter step would largely offset the financial burden of annually pre-funding retiree health care, thus addressing a long-standing complaint by the USPS and its union.
If it clears the House, this measure would still have to get through the Senate—where someone is bound to point out that it amounts to the bare, bare minimum necessary to keep the Postal Service afloat, not comprehensive reform. There’s no change to collective bargaining at the USPS, a major omission considering that personnel accounts for 80 percent of the agency’s costs. Also missing is any discussion of eliminating Saturday letter delivery. That common-sense change enjoys wide public support and would save the USPS $2 billion per year. But postal special-interest groups seem to have killed it, at least in the House. The emerging consensus around the bill is a sign that legislators are getting frightened about a politically embarrassing short-term collapse at the USPS. It is not, however, a sign that they’re getting serious about transforming the postal system for the 21st century.
In the last paragraph, the author seems to view legislators with _____.
A.respect.
B.tolerance.
C.discontent.
D.gratitude.
