Task: Question Answering
Input (English): passage: In 1908, the U.S. Congress rejected a proposal to make Mother's Day an official holiday, joking that they would also have to proclaim a ``Mother-in-law's Day''. However, owing to the efforts of Anna Jarvis, by 1911 all U.S. states observed the holiday, with some of them officially recognizing Mother's Day as a local holiday (the first being West Virginia, Jarvis' home state, in 1910). In 1914, Woodrow Wilson signed a proclamation designating Mother's Day, held on the second Sunday in May, as a national holiday to honor mothers.
