PROBLEM: 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?

SOLUTION: 1939 to 1941

PROBLEM: Passage: Flower ontogeny uses a combination of genes normally responsible for forming new shoots. The most primitive flowers probably had a variable number of flower parts, often separate from (but in contact with) each other. The flowers tended to grow in a spiral pattern, to be bisexual (in plants, this means both male and female parts on the same flower), and to be dominated by the ovary (female part). As flowers evolved, some variations developed parts fused together, with a much more specific number and design, and with either specific sexes per flower or plant or at least "ovary-inferior". Question: What did some plant parts do as they evolved?

SOLUTION: fused together

PROBLEM: Passage: After gaining the Master Sword, Link is cleansed of the magic that kept him in wolf form, obtaining the Shadow Crystal. Now able to use it to switch between both forms at will, Link is led by Midna to the Mirror of Twilight located deep within the Gerudo Desert, the only known gateway between the Twilight Realm and Hyrule. However, they discover that the mirror is broken. The Sages there explain that Zant tried to destroy it, but he was only able to shatter it into fragments; only the true ruler of the Twili can completely destroy the Mirror of Twilight. They also reveal that they used it a century ago to banish Ganondorf, the Gerudo leader who attempted to steal the Triforce, to the Twilight Realm when executing him failed. Assisted by an underground resistance group they meet in Castle Town, Link and Midna set out to retrieve the missing shards of the Mirror, defeating those they infected. Once the portal has been restored, Midna is revealed to be the true ruler of the Twilight Realm, usurped by Zant when he cursed her into her current form. Confronting Zant, Link and Midna learn that Zant's coup was made possible when he forged a pact with Ganondorf, who asked for Zant's assistance in conquering Hyrule. After Link defeats Zant, Midna recovers the Fused Shadows, but destroys Zant after learning that only Ganondorf's death can release her from her curse. Returning to Hyrule, Link and Midna find Ganondorf in Hyrule Castle, with a lifeless Zelda suspended above his head. Ganondorf fights Link by possessing Zelda's body and eventually by transforming into a beast, but Link defeats him and Midna is able to resurrect Zelda. Question: What is the only known gateway between Twilight Realm & Hyrule?

SOLUTION:
Gerudo Desert
