Problem: The UK political system, while technically a multi-party system, has functioned generally as a two-party (sometimes called a "two-and-a-half party") system; since the 1920s the two largest political parties have been the Conservative Party and the Labour Party. Before the Labour Party rose in British politics the Liberal Party was the other major political party along with the Conservatives. Though coalition and minority governments have been an occasional feature of parliamentary politics, the first-past-the-post electoral system used for general elections tends to maintain the dominance of these two parties, though each has in the past century relied upon a third party to deliver a working majority in Parliament. (A plurality voting system usually leads to a two-party system, a relationship described by Maurice Duverger and known as Duverger's Law.) There are also numerous other parties that hold or have held a number of seats in Parliament.
What was the only party that helped pass Duverger's Law?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
UN forces retreated to Suwon in the west, Wonju in the center, and the territory north of Samcheok in the east, where the battlefront stabilized and held. The PVA had outrun its logistics capability and thus were unable to press on beyond Seoul as food, ammunition, and materiel were carried nightly, on foot and bicycle, from the border at the Yalu River to the three battle lines. In late January, upon finding that the PVA had abandoned their battle lines, General Ridgway ordered a reconnaissance-in-force, which became Operation Roundup (5 February 1951). A full-scale X Corps advance proceeded, which fully exploited the UN Command's air superiority, concluding with the UN reaching the Han River and recapturing Wonju.
What caused General Ridgway to initiate Operation Roundup?
A: PVA had abandoned their battle lines

Context and question: One wave of the population boom ended abruptly in the mid-1980s, as oil prices fell precipitously. The space industry also suffered in 1986 after the Space Shuttle Challenger disintegrated shortly after launch. There was a cutback in some activities for a period. In the late 1980s, the city's economy suffered from the nationwide recession. After the early 1990s recession, Houston made efforts to diversify its economy by focusing on aerospace and health care/biotechnology, and reduced its dependence on the petroleum industry. Since the increase of oil prices in the 2000s, the petroleum industry has again increased its share of the local economy.
In what year did the space shuttle Challenger explode after launch?
Answer: 1986

Question: American political scientist Mark Cooper asserted that Nasser's charisma and his direct relationship with the Egyptian people "rendered intermediaries (organizations and individuals) unnecessary". He opined that Nasser's legacy was a "guarantee of instability" due to Nasser's reliance on personal power and the absence of strong political institutions under his rule. Historian Abd al-Azim Ramadan wrote that Nasser was an irrational and irresponsible leader, blaming his inclination to solitary decision-making for Egypt's losses during the Suez War, among other events. Miles Copeland, Jr. , once described as Nasser's closest Western adviser, said that the barriers between Nasser and the outside world have grown so thick that all but the information that attest to his infallibility, indispensability, and immortality has been filtered out.
Is there an answer to this question: What was needed under Nasser, the absence of which guaranteed instability?

Answer: strong political institutions
