A long and painful struggle with cancer and chemotherapy had caused baldness for Barbara Basset, of Mocrstown, NJ. The day her blond hair feel out in clumps was, for Barbara, the worst day of her ordeal. Detemined to use some form. of camouflage, she tried a wig but found it itchy and hot. Scarves slopped off or clung too tightly, accentuating the problem. Finally, a friend suggested Barbara call her neighbor, Marie Stevens, an accomplished seamstress who worked at home.
Barbara explained to Marie that she needed something between a scarf and a hat, with a shape that suggested hair beneath. It had to fasten securely, and had no opening that would reveal baldness. Sensing a kindred spirit, Marie agreed to work something up. She was no stranger to medical tragedy herself, having lost two of her seven children to cystic fibrosis.
The design itself was simple, a combination scarf/hat of light cotton and polyester that fit well, disguising the lack of hair. "Smart" was the description Barbara's friends came up with. For Barbara elegance was secondary to the scarf's greatest asset.
"That silly little hat saved me," she told friends.
Shortly after, Marie and Barbara formed a partnership selling the scarves, which they called Hide & Chic. They developed a line of colors, plus small elasticized versions for children. They had a brochure printed, and set it to oncology units and social-service directors in hospitals.
Soon after the company, Mare-bar, Inc. was on its feet, Barbara learned that her cancer had recurred . Despite more chemotherapy, she died, at age 40.
"She made me promise that I'd keep things going," Made says, "When she died, I was pretty low. But I kept getting mail from cancer patients who described how our scarf/hat had made Such a big difference. I got going again. It's a nice legacy for Barbara, who was a very special lady."
This passage is mainly about ______.

A. how Barbara became a fashion designer
B. how Marie helped Barbara recover from her illness
C. how Mare-bar Inc. came into being
D. how Barbara helped Marie to design the scarf/hat

It is hard to predict how science is going to turn out, and if it is really good science it is impossible to predict. If the things to be found are actually new, they are by definition unknown in advance. You cannot make choices in this matter. You either have science or you don't, and if you have it you are obliged to accept the surprising and disturbing pieces of information, along with the neat and promptly useful bits.
The only solid piece of scientific truth about which I feel totally confident is that we are profoundly ignorant about nature. Indeed, I regard this as the major discovery of the past hundred years of biology. It is, in its Way, an illuminating piece of news. It would have amazed the brightest minds of the 18th century Enlightenment to be told by any of us how little we know and how bewildering seems the way ahead. It is this sudden confrontation with the depth and scope of ignorance that represents the most significant contribution of the 20th century science to the human intellect. In earlier times, we either pretended to understand how things worked or ignored the problem, or simply made up stories to fill the gaps. Now that we have begun exploring in earnest, we are getting glimpses of how huge the questions are, and how far from being answered. Because of this, we are depressed. It is not so bad being ignorant if you are totally ignorant; the hard thing is knowing in some detail the reality of ignorance, the worst spots and here and there the not-so-bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted.
But we are making a beginning, and there ought to be some satisfaction. There are probably no questions we can think up that can't beanswered, sooner or later, including even the matter of consciousness. To be sure, there may well be questions we can't think up, ever and therefore limits to the reach of human intellect, but that is another matter. Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, and pay attention.
According to the author, really good science ______.

A. would surprise the brightest minds of the 18th century Enlightenment
B. will produce results which cannot be foreseen
C. will help people to make the right choice in advance
D. will bring about disturbing results
