(b) An astronaut weighs one-sixth as much on the Moon as on Earth.

(c) Ice floats on water,

(d) An old-fashioned hand pump cannot draw water from a well more than 34 ft deep.

Here we have to describe why is a quantitative observation more useful than a non-quantitative one and have to state which of the following are quantitative.

(a) The Sun rises in the east, (b) An astronaut weighs one-sixth as much on the Moon as on Earth (c) Ice floats on water, (d) An old-fashioned hand pump cannot draw water from a well more than 34 ft deep.

Step 1 of 2

Quantitative measurement is one by which we can count a quantity. It is more useful because by measuring the quantity we can get the accuracy of our result and the measured quantities can also be compared whereas non-quantitative measurement is the same as qualitative observation.
