Our attitudes toward the past and future shape our actions by the outcomes of our actions. For example, if you are nice and give a helping hand when needed, you will be rewarded with kindness back. Your actions in the past always affects your future. I hope this was what you were looking for

One of the purest relationships is the relationship of friendship. A person without a friend lives a hard life. Everybody needs a companion to deal with our experience. It is dependent upon you that how you define friendship. It can be sharing your food, taking care of that person, supporting them in their thick and thin. You may not be loud about it, but if you care for a person silently, that is what friendship is. Friendship is about laughing together on small things, cherishing every moment you share, standing together for each other even when the world turns their backs towards them.

Friendships are sometimes more durable than the relationship of love. Even though the definition of friendship varies from person to person, the core meaning behind it is the same for everybody. Life is empty without a friend. So when you gain a true friend, make sure you cherish it with all your heart. The person with a real friend, with whom all the things can be shared, are the luckiest in the world. A friend will never judge you, and they will never stop scolding you if you are wrong. But whatever the situation be, they will always be there to support you.

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.
Good deeds will be rewarded
