The correct answer is
the first option. Edgar Allan Poe uses fear to create a single effect in “The
Fall of the House of Usher”? <span>The single effect is a paradigm created
by Edgar Allan Poe that signifies that a story must produce one specific and
consistent effect in the reader. The fear as a single effect is unified in this
story through carefully chosen words when describing the characters, settings,
actions and writing dialogs. For example, throughout the story, reader can
sense the depression and fear surrounding every element in the house of Usher.</span>
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.
The answer would be "<span>Aiden is thrilled about starting a performance project on Romeo and Juliet, although he worries about getting assigned to a group of students who are poor actors." YOU'RE WELCOME :D
