Is it possible to make up for missed sleep on the weekends? Dr. Daniel Cohen investigated this prevalent belief by disrupting the circadian rhythms of a group of volunteers. Participants remained conscious for 33-hour stretches—equivalent to staying awake all night—and then slept for 10 hours. While the volunteers were awake, Cohen periodically tested their mental and motor skills. The sleep-deprived volunteers scored fairly well soon after waking, but as the hours wore on, the participants' ability to think clearly, as well as their reaction times, steadily worsened. The study implies that the chronically sleep-deprived may function normally for a short time but inevitably slow down, even if they attempt to catch up on their sleep.

in to words or less write a summary of chapter 6 of blood on the river

from Life on the Mississippi
I still keep in mind a certain wonderful sunset which I witnessed when steamboating was new to me. A broad expanse of the river was
turned to blood; in the middle distance the red hue brightened into gold, through which a solitary log came floating black and conspicuous; in one
place a long, slanting mark lay sparkling upon the water, in another the surface was broken by boiling, tumbling rings, that were as many-tinted as
an opal, where the ruddy flush was faintest, was a smooth spot that was covered with graceful circles and radiating lines, ever so delicately traced;
the shore on our left was densely wooded, and the sombre shadow that fell from this forest was broken in one place by a long ruffled trail that
shone like silver, and high above the forest wall a clean-stemmed dead tree waved a single leafy bough that glowed like a flame in the unobstructed
splendor that was flowing from the sun.....
The world was new to me, and I had never seen anything like this at home. But as I have said, a day came when I began to cease from noting
the glories and the charms which the moon and the sun and the twilight wrought upon the river's face, another day came when I ceased altogether
to note them. Then, if that sunset scene had been repeated, I should have looked upon it without rapture, and should have commented upon it,
inwardly, after this fashion. This sun means that we are going to have wind to-morrow, that floating log means that the river is rising small thanks
to it that starting mark on the water refers to a bluff reef which is going to kill somebody's steamboat che of these nights, if it keeps on stretching
out like that, those tumbling "bolls" show a dissolving bar and a changing channel there, the lines and circles in the slick water over yonder are a
warring that the troublesome place is shoaling up dangerously,
Which statement best conveys how the author's viewpoint changes in the passage?
1. His fear of nature intensifies as he comes to accept that a river is more dangerous than it is beautiful.
O2. His ability to describe the river with precise language improves as he gains more skills in steamboating
3. His way of seeing the river shifts from mysterious wonder to objective analysis as he becomes a steamboating expert
4. His enjoyment of the river comes at first as the result of acute observations and later as the result of proven instincts.
