Problem: IPod:

iPods have won several awards ranging from engineering excellence,[not in citation given] to most innovative audio product, to fourth best computer product of 2006. iPods often receive favorable reviews; scoring on looks, clean design, and ease of use. PC World says that iPod line has "altered the landscape for portable audio players". Several industries are modifying their products to work better with both the iPod line and the AAC audio format. Examples include CD copy-protection schemes, and mobile phones, such as phones from Sony Ericsson and Nokia, which play AAC files rather than WMA.

What file format is not supported by Sony Ericsson and Nokia?
---
A: WMA

Problem: Once food leaves the crop, it passes to the midgut (element 13 in numbered diagram), also known as the mesenteron, where the majority of digestion takes place. Microscopic projections from the midgut wall, called microvilli, increase the surface area of the wall and allow more nutrients to be absorbed; they tend to be close to the origin of the midgut. In some insects, the role of the microvilli and where they are located may vary. For example, specialized microvilli producing digestive enzymes may more likely be near the end of the midgut, and absorption near the origin or beginning of the midgut.:32
Food goes in to the midgut after leaving where?

Answer: the crop

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
For some species of waders, migration success depends on the availability of certain key food resources at stopover points along the migration route. This gives the migrants an opportunity to refuel for the next leg of the voyage. Some examples of important stopover locations are the Bay of Fundy and Delaware Bay.
What does successful migration depend on for some waders?
A: the availability of certain key food resources

Context and question: More-or-less independent circadian rhythms are found in many organs and cells in the body outside the suprachiasmatic nuclei (SCN), the "master clock". These clocks, called peripheral oscillators, are found in the adrenal gland,[citation needed] oesophagus, lungs, liver, pancreas, spleen, thymus, and skin.[citation needed] Though oscillators in the skin respond to light, a systemic influence has not been proven. There is also some evidence that the olfactory bulb and prostate may experience oscillations when cultured, suggesting that these structures may also be weak oscillators.[citation needed]
What in the skin responds to temperature?
Answer: unanswerable

Question: At times when a death sentence is affirmed on direct review, it is considered final. Yet, supplemental methods to attack the judgment, though less familiar than a typical appeal, do remain. These supplemental remedies are considered collateral review, that is, an avenue for upsetting judgments that have become otherwise final. Where the prisoner received his death sentence in a state-level trial, as is usually the case, the first step in collateral review is state collateral review. (If the case is a federal death penalty case, it proceeds immediately from direct review to federal habeas corpus.) Although all states have some type of collateral review, the process varies widely from state to state. Generally, the purpose of these collateral proceedings is to permit the prisoner to challenge his sentence on grounds that could not have been raised reasonably at trial or on direct review. Most often these are claims, such as ineffective assistance of counsel, which requires the court to consider new evidence outside the original trial record, something courts may not do in an ordinary appeal. State collateral review, though an important step in that it helps define the scope of subsequent review through federal habeas corpus, is rarely successful in and of itself. Only around 6 percent of death sentences are overturned on state collateral review. In 2010, the death sentences of 53 inmates were overturned as a result of legal appeals or high court reversals.
Is there an answer to this question: When a prisoner is given a death sentence in a state, what is the last step of collateral review?

Answer: unanswerable

Problem: Molotov%E2%80%93Ribbentrop Pact:

In an effort to demonstrate peaceful intentions toward Germany, on 13 April 1941, the Soviets signed a neutrality pact with Axis power Japan. While Stalin had little faith in Japan's commitment to neutrality, he felt that the pact was important for its political symbolism, to reinforce a public affection for Germany. Stalin felt that there was a growing split in German circles about whether Germany should initiate a war with the Soviet Union. Stalin did not know that Hitler had been secretly discussing an invasion of the Soviet Union since summer 1940, and that Hitler had ordered his military in late 1940 to prepare for war in the east regardless of the parties' talks of a potential Soviet entry as a fourth Axis Power.

Who did the Soviet Union disagree to remain neutral with when they signed a treaty on the 13th of April?

A:
unanswerable
