Answer: D. The resolute desk has a fascinating history
Explanation:
This double pedestal partners' desk, usually called the "Resolute desk", was made from the oak timbers of the British ship H.M.S. Resolute as a gift to President Rutherford B. Hayes from Queen Victoria in 1880.
This desk remained, however, on the Second Floor of the Residence in the President's Study.
It is A because it restates the noun, CAT, with a different name, CALICO. It is also A because WHICH is a relative pronoun.
Answer:
The most logical answer would be to tell a relative about the places the person visited while on summer vacation.

Answer:
Drop each ball from the platform three more times
Explanation:
Reliability or precision means how much the measured values vary from each other when measured by performing the same experiment repeatedly.
When measuring values by observation in physical experiments of this nature, it is best to perform the experiment and measure the values at least three times. The more the better.
In such measurements there is always a margin of error, e.g how at exact time you start and stop the stop-watch. There may also be a but harder or softer side of ball (tennis ball strip) touching the ground. In order to minimize such and some other margin of errors, it is advisable to measure the values more than 3-4 times, and then take their mean. The value now obtained would be would reliable or precise.
Second and third options are incorrect because they will have no effect on improving the reliability.
In order for the fourth option to be correct, the other people need to do the same (not similar) experiment, with the same balls and same conditions/instruments. That would be equivalent to repeating the experiment 3-4 times, which is already covered by first option.
