　　[ C] or D.. Mark your answers on ANSWER SHEET.

　　Text 1

　　A finding in recent years shows that men cannot manufacture blood as efficiently as women

　　can. This makes surgery riskier for men. Because they do not breathe as often as women, men also need more oxygen. But men breathe more deeply and this exposes them to another risk. They draw more of the air when it is polluted.

　　Men's bones are larger than women's and they are arranged somewhat differently. The feminine walk that evokes so many whistles is a matter of bone structure. A man has broader shoulders and a narrower pelvis, which makes him stride out with no waste motion. A woman's wider pelvis, designed for childbearing, forces her to put more movement into each step she takes with the result that she displays a bit of jiggle and sway as she walks.

　　If you think a man is brave because he can climb a ladder to clean out the roof gutters, don't forget it is easier for him than for a woman. The angle at which a woman's thigh is joined to her knees makes climbing difficult for her, no matter whether it is a ladder or stairs or a mountain that she is tackling.

　　A man's skin is thicker than a woman's and not nearly as soft. This prevents the sun's radiation from getting through, which is why men wrinkle less than women do. Women have a thin by- er of fat just under the skin and there is a plus to this greater fat reserve. It acts as an invisible ful coat to keep a woman wanner in the winter. Women also stay cooler in summer. Because the far layer helps insulate them against heat. Men's fat is distributed differently. And they do not have that layer of it underneath their skin. In fact, they have considerably less fat than women and more lean mass. 41 percent of a man's body is muscle compared to thirty-five percent for women, which means that men have more muscle power. When we mention strength, almost 90 percent of a man's weight is strength compared to about 50 percent of a woman's weight.

　　The higher proportion of muscle to fat makes it easier for men to lose weight. Muscle burns up five more calories a pound than fat does just to maintain itself. So when a man wants to lose

　　weight, the pounds roll off much faster. For all men's muscularity they do not have the energy reserves women do. They have more start-up energy, but the fat tucked away in women's nooks and crannies provides a rich energy reserve that men lack.

　　Cardiologists at the University of Alabama who tested healthy women on treadmills discovered that over the years the female capacity for exercise far exceeds the male capacity. A woman of sixty who is in good health can exercise up to 90 percefit of what she could do when she was twenty.

　　A man of sixty has only 60 percent left of his capacity as a twenty-year-old.

　　Text 2

　　Text 3

　　I remember the way the light touched her hair. She turned her head, and our eyes met, a momentary awareness in that raucous fifth grade classroom. I felt as though I' d been struck a blow under the heart Thus began my first love affair.

　　Her name was Rachel, and I mooned my way through the grade and high school, stricken at the mere sight of her, tongue-tied in her presence. Does anyone, anymore, linger in the shadows of evening, drawn by the pale light of a window--her window--like some hapless summer insect?

　　That delirious swooning, asexual but urgent and obsessive, that made me awkward and my voice crack, is like some impossible dream now.

　　I would catch sight of her, walking down an aisle of trees to or from school, and I' d become paralyzed. She always seemed so poised, so self-possessed. At home, I' d relive each encounter,

　　writhing at the thought of my inadequacies. We eventually got acquainted and socialized as we entered our adolescence, she knew I had a case on her, and I sensed her affectionate tolerance for me. "Going sready" implied a maturity we still lacked. Her Orthodox Jewish upbringing and my

　　own Catholic scruples imposed an inhibited grace that made even kissing a distant prospect, however fervently desired. I managed to hold her once at a dance-chaperoned, of course. Our embrace made her giggle, a sound so trusting that I hated myself for what I' d been thinking. At any rate,my love for Rachel remained unrequited. We graduated from high school, she went on to college,and I joined the Army.

　　When World War II engulfed us, I was sent overseas. For a time we corresponded, and her letters were the highlight of those grinding endless years. Once she sent me a snapshot of herself in a bathing suit, which drove me to the wildest of fantasies. I mentioned the possibility of marriage in my next letter, and almost immediately her replies became less frequent, less personal. Her Dear

　　John latter finally caught UD with me while I was awaiting discharge. She gently explained the impossibility of a marriage between us. Looking back on it, I must have recovered rather quickly, although for the first few months I believed I didn' t want to five. Like Rachel, I found someone else, whom I learned to love with a deep and permanent commitment that has lasted to this day.
