Passage: Double deck elevators are used in the Taipei 101 office tower. Tenants of even-numbered floors first take an escalator (or an elevator from the parking garage) to the 2nd level, where they will enter the upper deck and arrive at their floors. The lower deck is turned off during low-volume hours, and the upper deck can act as a single-level elevator stopping at all adjacent floors. For example, the 85th floor restaurants can be accessed from the 60th floor sky-lobby. Restaurant customers must clear their reservations at the reception counter on the 2nd floor. A bank of express elevators stop only on the sky lobby levels (36 and 60, upper-deck car), where tenants can transfer to "local" elevators. Question: What levels make up the "sky lobby"?

Ex Output:
36 and 60, upper-deck car

Passage: 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. Question: What was the other major party before the Labour party?

Ex Output:
Liberal Party
