This task is about writing a correct answer for the reading comprehension task. Based on the information provided in a given passage, you should identify the shortest continuous text span from the passage that serves as an answer to the given question. Avoid answers that are incorrect or provides incomplete justification for the question.

Q: Passage: The UAP had been formed as a new conservative alliance in 1931, with Labor defector Joseph Lyons as its leader. The stance of Lyons and other Labor rebels against the more radical proposals of the Labor movement to deal the Great Depression had attracted the support of prominent Australian conservatives. With Australia still suffering the effects of the Great Depression, the newly formed party won a landslide victory at the 1931 Election, and the Lyons Government went on to win three consecutive elections. It largely avoided Keynesian pump-priming and pursued a more conservative fiscal policy of debt reduction and balanced budgets as a means of stewarding Australia out of the Depression. Lyons' death in 1939 saw Robert Menzies assume the Prime Ministership on the eve of war. Menzies served as Prime Minister from 1939 to 1941 but resigned as leader of the minority World War II government amidst an unworkable parliamentary majority. The UAP, led by Billy Hughes, disintegrated after suffering a heavy defeat in the 1943 election. Question: What years did Robert Menzies serve as Prime Minister?

A: 1939 to 1941

Q: Passage: Indian astronomer and mathematician Aryabhata (476-550), in his Aryabhatiya (499) introduced a number of trigonometric functions (including sine, versine, cosine and inverse sine), trigonometric tables, and techniques and algorithms of algebra. In 628 AD, Brahmagupta suggested that gravity was a force of attraction. He also lucidly explained the use of zero as both a placeholder and a decimal digit, along with the Hindu-Arabic numeral system now used universally throughout the world. Arabic translations of the two astronomers' texts were soon available in the Islamic world, introducing what would become Arabic numerals to the Islamic World by the 9th century. During the 14th–16th centuries, the Kerala school of astronomy and mathematics made significant advances in astronomy and especially mathematics, including fields such as trigonometry and analysis. In particular, Madhava of Sangamagrama is considered the "founder of mathematical analysis". Question: What did Brahmagupta use the number zero for?

A: a placeholder and a decimal digit

Q: Passage: The Faraday constant F is the charge of one mole of electrons, equal to the Avogadro constant NA multiplied by the elementary charge e. It can be determined by careful electrolysis experiments, measuring the amount of silver dissolved from an electrode in a given time and for a given electric current. In practice, it is measured in conventional electrical units, and so given the symbol F90. Substituting the definitions of NA and e, and converting from conventional electrical units to SI units, gives the relation to the Planck constant. Question: How is the Farday constant value quickly calculated?

A:
the Avogadro constant NA multiplied by the elementary charge e
