In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Input: Consider Input: What posthumous service did Lowe perform on Whitehead's behalf?, Context: The two volume biography of Whitehead by Victor Lowe is the most definitive presentation of the life of Whitehead. However, many details of Whitehead's life remain obscure because he left no Nachlass; his family carried out his instructions that all of his papers be destroyed after his death. Additionally, Whitehead was known for his "almost fanatical belief in the right to privacy", and for writing very few personal letters of the kind that would help to gain insight on his life. This led to Lowe himself remarking on the first page of Whitehead's biography, "No professional biographer in his right mind would touch him."

Output: biography


Input: Consider Input: Where does Elizabeth live?, Context: Elizabeth's personal fortune has been the subject of speculation for many years. Jock Colville, who was her former private secretary and a director of her bank, Coutts, estimated her wealth in 1971 at £2 million (equivalent to about £25 million today). In 1993, Buckingham Palace called estimates of £100 million "grossly overstated". She inherited an estimated £70 million estate from her mother in 2002. The Sunday Times Rich List 2015 estimated her private wealth at £340 million, making her the 302nd richest person in the UK.

Input: Consider Input: Which letter is somewhat important to Latimer's work?, Context: Lewis Latimer, employed at the time by Edison, developed an improved method of heat-treating carbon filaments which reduced breakage and allowed them to be molded into novel shapes, such as the characteristic "M" shape of Maxim filaments. On 17 January 1882, Latimer received a patent for the "Process of Manufacturing Carbons", an improved method for the production of light bulb filaments, which was purchased by the United States Electric Light Company. Latimer patented other improvements such as a better way of attaching filaments to their wire supports.


Output: "M"
