Input: Consider Input: Passage: The northern segment of the fault runs from Hollister, through the Santa Cruz Mountains, epicenter of the 1989 Loma Prieta earthquake, then up the San Francisco Peninsula, where it was first identified by Professor Lawson in 1895, then offshore at Daly City near Mussel Rock. This is the approximate location of the epicenter of the 1906 San Francisco earthquake. The fault returns onshore at Bolinas Lagoon just north of Stinson Beach in Marin County. It returns underwater through the linear trough of Tomales Bay which separates the Point Reyes Peninsula from the mainland, runs just east of Bodega Head through Bodega Bay and back underwater, returning onshore at Fort Ross. (In this region around the San Francisco Bay Area several significant "sister faults" run more-or-less parallel, and each of these can create significantly destructive earthquakes.) From Fort Ross, the northern segment continues overland, forming in part a linear valley through which the Gualala River flows. It goes back offshore at Point Arena. After that, it runs underwater along the coast until it nears Cape Mendocino, where it begins to bend to the west, terminating at the Mendocino Triple Junction.
 Link Information: The Gualala River is a river on the northern coast of California. Most of the river is in Sonoma County, but a portion is in Mendocino County. The headwaters of the 40 mi river ( Answer: 40

Output: How long is the Gualala River?


Input: Consider Input: Passage: Born in 1941, Belanger attended public schools in Bristol, Connecticut. He has degrees from Haverford College (A.B., 1963) and from Columbia University (M.A., 1964; Ph.D., 1970), where he studied under James L. Clifford, Allen T. Hazen, and John H. Middendorf. Between 1966 and 1971, while working on his dissertation on aspects of the 18th-century London book trade, he taught advanced prose composition courses at the Columbia University School of General Studies, an activity leading to the 1972 publication of The Art of Persuasion, a writing manual co-authored with J. Steward LaCasce. While in England on a Columbia traveling fellowship in 1968–69, he revised the book production sections of the 18th-century volume of the New Cambridge Bibliography of English Literature (NCBEL), working with Graham Pollard, who had compiled the original sections for the first edition of CBEL, published in 1940. With Jane Marla Robbins, he co-authored and co-directed a one-character play starring Robbins called Dear Nobody, based on the life of the 18th-century diarist and novelist, Fanny Burney. The play ran Off-Off-Broadway in 1968; it later had a five-months' Off-Broadway run at the Cherry Lane Theatre in 1974.

Input: Consider Input: Passage: The 1966 NBA draft was the 20th annual draft of the National Basketball Association (NBA). The draft was held on May 11 and 12, 1966 before the 1966–67 season. In this draft, ten NBA teams took turns selecting amateur U.S. college basketball players. A player who had finished his four-year college eligibility was eligible for selection. If a player left college early, he would not be eligible for selection until his college class graduated. The first two picks in the draft belonged to the teams that finished last in each division, with the order determined by a coin flip. The New York Knicks won the coin flip and were awarded the first overall pick, while the Detroit Pistons were awarded the second pick. This draft was the first to use the coin flip method, which replace the territorial pick rule. The remaining first-round picks and the subsequent rounds were assigned to teams in reverse order of their win–loss record in the previous season. An expansion franchise, the Chicago Bulls, took part in the NBA Draft for the first time and were assigned the last pick of each round. The draft consisted of 19 rounds comprising 112 players selected.
