TEXT C
It’s the 24th century, and aboard the U.S.S. Enterprise, Star Trek chief engineer Geordi LaForge scans the heavens by means of the sophisticated prosthetic lenses that give him superhuman vision. That may be science fiction, but we mere myopes of the 21st century may not have to wait 300 years before we can boldly see where no one has seen before. A new high-performance contact lens under development at the department for applied physics at the University of Heidelberg will not only correct ordinary vision defects but will enhance normal night vision as much as five times, making people’s vision sharper than that of cats, owls -- and Goerdi LaForge.
Josef Bille, a 54-year-old physics professor, and his colleagues at the university hope that their ultra-customized vision aids will enable hunters to better spot their quarry at dawn, campers to pitch-their tents at dusk without flashlights, drivers to make out the road ahead with more ease and persons suffering from night blindness to see in the dark. Theatergoers might also benefit: the lenses work best when the pupils are fully dilated as when looking at a lighted stage from the depths of a dark auditorium. "Forget opera glasses," crows Bille, "they will no longer be necessary."
Bille and his team work with an optical instrument called an active mirror -- a device used in astronomical telescopes to spot fledgling stars and far distant galaxies. Connected to a wavefront sensor that tracks and measures the course of a laser beam into the eye and back, the aluminum mirror detects the deficiencies of the cornea, the transparent membrane that covers the lens of the human eye. The highly precise data from the two instruments -- which, Bille hopes, will one day be found at opticians all over the world -- serve as a basis for the production of completely individualized contact lenses that correct and enhance vision so well that the wearer’s sight is actually better than nature’s perfect 20-20.

TEXT D
The push for men to express their feelings presumes that we have feelings and we do have a few, but they remain submerged, and the airing of them often violates their authenticity. We are, as a gender, as dull as we seem. Contrary to the claptrap of the men’s movement, men gain power through not talking. "The strength of the genie," said poet Richard Wilbur, "comes from being in a bottle." I’m no biologist, but my guess is that the male human animal was programmed for silence. One can make us talk counter to our genetic makeup, but it is like training kangaroos to box. It’s mildly entertaining but pointless.
There’s a deep, basically serene well of silence in most men, which, for better and worse, is where we live. I do not mean to start clap-trapping myself, but I often think that all our acts of aggression and posturing arise from that well as forms of overcompensation of panic. Unlike women, men are not social creatures, not born administrators. It’s politically correct to think of God as female, but no woman would have thrown Lucifer out of heaven; she would have offered him a desk job. Had Lucifer been a woman, she would have dropped all that "myself am hell" business and taken it.
I would go so far as to argue that men were programmed to be isolated from one another and that aloneness is our natural state. Silence in male friendships is our way of being alone with each other. Once men have established a friendship, that itself is the word. The affection is obvious, at least to us. A main component of our silence is an appreciation of the obvious.
77. Which of the following statements about men is true?
A. Men are talkative.
B. Men are powerful.
C. Men are reticent.
D. Men are authentic.

D. Men enjoy keeping the genie in a bottle.
