(a) Walter likes very much to go on visits to his grandmother, because she always tells him many funny stories.
(b) Yesterday I saw a pretty little dog in the street. It had curly brown hair, short legs, and a long tail.
Credit if one sentence is repeated without a single error.
Alt. 2. Comprehension of Physical Relations
(a) Draw a horizontal line 6 or 8 inches long. An inch or two above it draw a horizontal line about an inch long parallel to the first. Say, "The long line represents the perfectly level ground of a field, and the short line represents a cannon. The cannon is pointed horizontally (on a level) and is fired across this perfectly level field." After it is clear that these conditions of the problem are comprehended, add, "Now, suppose that this cannon is fired off and that the ball comes to the ground at this point here (pointing to the farther end of the line which represents the field). Take this pencil and draw a line which will show what path the cannon ball will take from the time it leaves the mouth of the cannon till it strikes the ground."
(b) Say, "You know, of course, that water holds up a fish that is placed in it. Well, here is a problem: Suppose we have a bucket which is partly full of water. We place the bucket on the scales and find that with the water in it it weighs exactly 45 pounds. Then we put a 5-pound fish into the bucket of water. Now, what will the whole thing weigh?" If S. responds correctly, say, "How can this be correct, since the water itself holds up the fish?"
(c) "You know, do you not, what it means when they say a gun 'carries 100 yards?' It means that the bullet goes 100 yards before it drops to amount to anything." When this is clear, proceed, "Now, suppose a man is shooting at a mark about the size of a quart can. His rifle carries perfectly more than 100 yards. With such a gun is it any harder to hit the mark at 100 yards than it is at 50 yards?"
Credit if two of the three problems are satisfactorily solved.
For (a), line must begin almost on a level and drop more rapidly toward the end.
For (b), S. must adhere positively to right answer.
