Some rock formations in the path of a glacier are sculpted into small hills called roche moutonnee, or "sheepback" rock. Roche moutonnee are elongated, rounded, and asymmetrical bedrock knobs that can be produced by glacier erosion. They range in length from less than a meter to several hundred meters long. Roche moutonnee have a gentle slope on their up-glacier sides and a steep to vertical face on their down-glacier sides. The glacier abrades the smooth slope on the upstream side as it flows along, but tears loose and carries away rock from the downstream side via plucking.
What are roche moutonnee?
A: elongated, rounded, and asymmetrical bedrock knobs that can be produced by glacier erosion

Washington, D.C. is often mentioned as a candidate for statehood. In Federalist No. 43 of The Federalist Papers, James Madison considered the implications of the definition of the "seat of government" found in the United States Constitution. Although he noted potential conflicts of interest, and the need for a "municipal legislature for local purposes," Madison did not address the district's role in national voting. Legal scholars disagree on whether a simple act of Congress can admit the District as a state, due to its status as the seat of government of the United States, which Article I, Section 8 of the Constitution requires to be under the exclusive jurisdiction of Congress; depending on the interpretation of this text, admission of the full District as a state may require a Constitutional amendment, which is much more difficult to enact. However, the Constitution does not set a minimum size for the District. Its size has already changed once before, when Virginia reclaimed the portion of the District south of the Potomac. So the constitutional requirement for a federal district can be satisfied by reducing its size to the small central core of government buildings and monuments, giving the rest of the territory to the new state.
Who can admit the District as a Federalist No. 43?
A: unanswerable

Because of the above issues, Nigeria's political parties are pan-national and secular in character (though this does not preclude the continuing preeminence of the dominant ethnicities). The major political parties at that time included the then ruling People's Democratic Party of Nigeria, which maintains 223 seats in the House and 76 in the Senate (61.9% and 69.7% respectively); the opposition formerly All Nigeria People's Party now All Progressives Congress has 96 House seats and 27 in the Senate (26.6% and 24.7%). About twenty minor opposition parties are registered.
How many minor opposition parties does Nigeria have?
A: About twenty

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.
What is an example of an issue that isn't raised in collateral review?
A:
