Read a paragraph from an essay supporting Truman’s decision to use the atomic bomb against Japan during World War II.

[1] Many people have argued that nothing could justify the president’s use of the atomic bomb because it killed so many innocent civilians. [2] Truman himself refused to drop a third atomic bomb on Japan because he was horrified by the death and devastation it had caused. [3] However, he never regretted his decision to use it in the first place. [4] Using the bomb brought an immediate end to a war that might have gone on for months or even years longer. [5] It is impossible to put a number on how many more deaths the continuing war might have caused, but there are indications. [6] Millions had already died in the Pacific theater. [7] Whenever US troops invaded an island, they knew the fight was to the death. [8] In the battle for Okinawa alone, there had been almost 50,000 US casualties, while Japan had suffered some 90,000 military deaths and at least 100,000 civilian deaths. [9] With his decision, Truman put an end to the slaughter.

What is fertility?

Fertility can be understood as the capability to produce offspring through reproduction following the onset of sexual maturity. The fertility rate is the average number of children born by a female during her lifetime and is quantified demographically. Fertility is addressed when there is a difficulty or an inability to reproduce naturally, which is referred to as infertility.

Infertility is widespread, with fertility specialists available all over the world to assist mothers and couples who experience difficulties having a baby. Human fertility depends on factors of nutrition, sexual behaviour, consanguinity, culture, instinct, endocrinology, timing, economics, personality, way of life, and emotions. Fertility differs from fecundity, which is defined as the potential for reproduction.

Where a woman or the lack of fertility is infertility while a lack of fecundity would be called sterility.

6. Thirty random college students are asked if they study during the week. Since 60% said yes, a statement can be made that 40% of students only study on the weekend.

Answers

Answer: False

Explanation:

Such a statement cannot be made as it would mean that the results were misinterpreted. The survey asked students if they studied in the week not if they studied in the weekend therefore simply inferring from those who said they studied during the week would be an error.

Some of the 60% who study in the week might also study during the weekend which would increase the 40% figure said to study in the weekend. Some of the students who said they don't study in the week might not study in the weekend either thereby reducing the 40% figure. For these two reasons and others, this statement cannot be made.
