Answer 1

In a first-past-the-post (FPTP or FPP; sometimes formally called single-member plurality voting or SMP) electoral system, voters cast their vote for a candidate of their choice, and the candidate who receives the most votes wins. FPTP is a plurality voting method, and is primarily used in systems that use single-member electoral divisions. FPTP is used as the primary form of allocating seats for legislative elections in about a third of the world's countries, mostly in the English-speaking world (the United States, the United Kingdom, Canada, India, Pakistan, and other countries in the Commonwealth of Nations).
