Final answer:
Cabinet Ministers are chosen by the Prime Minister, who selects from the members of the government, and the choice is influenced by political considerations and expertise in the relevant areas.
Step-by-step explanation:
A Cabinet Minister is chosen by the Prime Minister in a parliamentary system. The Prime Minister selects Cabinet Ministers from among the members of the government, often from the same political party. These ministers are expected to have expertise in the areas they oversee. The Prime Minister's choice is influenced by the political landscape and the need to balance representation from various factions and regions. Unlike in presidential systems where appointments can also come from outside the political realm, parliamentary systems usually require that Cabinet Ministers be sitting members of the parliament. In either case, the selection of Cabinet Ministers is an important political decision that reflects the dynamics and needs of the governing party and the country.
