Problem: Guests ascending to the 67th, 69th, and 70th level observation decks (dubbed "Top of the Rock") atop the GE Building at Rockefeller Center in New York City ride a high-speed glass-top elevator. When entering the cab, it appears to be any normal elevator ride. However, once the cab begins moving, the interior lights turn off and a special blue light above the cab turns on. This lights the entire shaft, so riders can see the moving cab through its glass ceiling as it rises and lowers through the shaft. Music plays and various animations are also displayed on the ceiling. The entire ride takes about 60 seconds.
What are the 67th, 69th, and 70th floors of the GE Building at Rockerfeller Center nicknamed?
The answer is the following: "Top of the Rock"

Problem: It is now known that the molecular circadian clock can function within a single cell; i.e., it is cell-autonomous. This was shown by Gene Block in isolated mollusk BRNs.[clarification needed] At the same time, different cells may communicate with each other resulting in a synchronised output of electrical signaling. These may interface with endocrine glands of the brain to result in periodic release of hormones. The receptors for these hormones may be located far across the body and synchronise the peripheral clocks of various organs. Thus, the information of the time of the day as relayed by the eyes travels to the clock in the brain, and, through that, clocks in the rest of the body may be synchronised. This is how the timing of, for example, sleep/wake, body temperature, thirst, and appetite are coordinately controlled by the biological clock.[citation needed]
How are sleep and wake cycles as well as body functions coordinated?
The answer is the following: biological clock

Problem: As the Romans extended their dominance throughout the Mediterranean world, their policy in general was to absorb the deities and cults of other peoples rather than try to eradicate them, since they believed that preserving tradition promoted social stability. One way that Rome incorporated diverse peoples was by supporting their religious heritage, building temples to local deities that framed their theology within the hierarchy of Roman religion. Inscriptions throughout the Empire record the side-by-side worship of local and Roman deities, including dedications made by Romans to local gods. By the height of the Empire, numerous international deities were cultivated at Rome and had been carried to even the most remote provinces, among them Cybele, Isis, Epona, and gods of solar monism such as Mithras and Sol Invictus, found as far north as Roman Britain. Because Romans had never been obligated to cultivate one god or one cult only, religious tolerance was not an issue in the sense that it is for competing monotheistic systems. The monotheistic rigor of Judaism posed difficulties for Roman policy that led at times to compromise and the granting of special exemptions, but sometimes to intractable conflict. For example, religious disputes helped cause the First Jewish–Roman War and the Bar Kokhba revolt.
What did the Romans tend to do with local religions and deities in conquered areas? 
The answer is the following: absorb

Problem: Napoleon would end up leaving Iberia in order to deal with the Austrians in Central Europe, but the Peninsular War continued on long after his absence. He never returned to Spain after the 1808 campaign. Several months after Corunna, the British sent another army to the peninsula under the future Duke of Wellington. The war then settled into a complex and asymmetric strategic deadlock where all sides struggled to gain the upper hand. The highlight of the conflict became the brutal guerrilla warfare that engulfed much of the Spanish countryside. Both sides committed the worst atrocities of the Napoleonic Wars during this phase of the conflict. The vicious guerrilla fighting in Spain, largely absent from the French campaigns in Central Europe, severely disrupted the French lines of supply and communication. Although France maintained roughly 300,000 troops in Iberia during the Peninsular War, the vast majority were tied down to garrison duty and to intelligence operations. The French were never able to concentrate all of their forces effectively, prolonging the war until events elsewhere in Europe finally turned the tide in favor of the Allies. After the invasion of Russia in 1812, the number of French troops in Spain vastly declined as Napoleon needed reinforcements to conserve his strategic position in Europe. By 1814, after scores of battles and sieges throughout Iberia, the Allies had managed to push the French out of the peninsula.
 In what year did the invasion of Russia take place?
The answer is the following:
1812
