In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.

Question: How many children did the Dutch naturalist have? Passage 1:The yellow-wattled lapwing was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his Histoire Naturelle des Oiseaux in 1781. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle. This plate was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Charadrius malabaricus in his catalogue of the Planches Enluminées. The type locality is the Malabar Coast in southwest India. The current genus Vanellus was erected by the French zoologist Mathurin Jacques Brisson in 1760. Vanellus is the Medieval Latin for a "lapwing". It is a diminutive of the Latin vanus meaning "winnowing" or "fan". The species is monotypic.
 Passage 2:Samuelson was born on a dairy farm in Ontario, Wisconsin, near LaCrosse. He considered becoming a Lutheran pastor before deciding on six months of radio school. His early work was based in Wisconsin, at WKLJ in Sparta, WHBY in Appleton, and WBAY-TV/AM in Green Bay. He is best known for his association with WGN Radio in Chicago, serving as the station's head agriculture broadcaster since 1960. In May of 1960, one of Mr. Samuelson's first assignments for WGN was to Emcee the National Barn Dance, a long running program that WGN had just acquired when WLS radio discontinued its association with Prairie Farmer Magazine. WLS had become "The Station With Personality" and started playing Rock and Roll. Three years into his tenure at WGN, he was the staffer that read the news of the John F. Kennedy assassination. He currently co-hosts (with associate Max Armstrong) the Morning Show on Saturdays. In addition, Samuelson hosts a three-minute daily "National Farm Report", and a weekly commentary, "Samuelson Sez"; both are syndicated to various stations across the country through Tribune Broadcasting's Tribune Radio Network.
 Passage 3:Additional specimens - a lower jaw from a juvenile specimen, UMNH.VP.26010, and a juvenile femur, UMNH.VP.26011 - were also referred to the same taxon. In 2017, all of these specimens were described by Rafael Royo-Torres, Paul Upchurch, James Kirkland, Donald DeBlieux, John Foster, Alberto Cobos, and Luis Alcalá as part of a research paper published in Scientific Reports. They named a new genus for the specimens, Mierasaurus; the name honors Bernardo de Miera y Pacheco, a Spanish cartographer who was "the first European scientist to enter what is now Utah" in the Domínguez–Escalante expedition of 1776. They also named the type and only species M. bobyoungi after Robert ("Bob") Young, in order to acknowledge "the importance of [his] underappreciated research" the geology of the Early Cretaceous of Utah.
