Question: Which house of the Nevada legislature is Olivia Diaz a member of?
Context: Sadie Dotson Hurst (July 27, 1857 – January 17, 1952) was a US politician.  Endorsed by the "Nevada State Journal", she was the first woman elected to the Nevada Legislature (R-Washoe).  When the legislature met in special session on February 7, 1919 to ratify the Federal Suffrage Amendment, it was Hurst, the assemblywoman from Reno, who presented the resolution.  She had a further distinction of being the first woman to preside over a state Legislature during the ratification of the Federal Suffrage Amendment.  At the time, she was not only Nevada's first assemblywoman but also its only one, having been picked by the Women Citizens' Club of Reno, to bring women into the legislature.  She also was the member of the Nevada Legislature who presented the bill to raise the age of consent for girls from 16 to 18, a bill which passed both houses and was signed by the Governor.  Born in Iowa in 1857, Hurst died in Pasadena, California in 1952. The Nevada Senate is the upper house of the Nevada Legislature, the state legislature of U.S. state of Nevada.  The Senate currently (2012-2021) consists of 21 members from single-member districts.  In the previous redistricting (2002-2011) there were 19 districts, two of which were multimember.  Since 2012, there have been 21 districts, each formed by combining two neighboring Assembly districts.  Each senator represented approximately 128,598 as of the 2010 census.  Article Four of The Nevada Constitution sets that Senators serve staggered four-year terms.  In addition, the size of the Senate is set to be no less than one-third and no greater than one-half of the size of the Assembly.  Term limits, limiting senators to three 4-year terms (12 years), took effect in 2010.  Because of the change in Constitution, seven senators were termed out in 2010, four were termed out in 2012, and one was termed out in 2014.  The Senate met at the Nevada State Capitol in Carson City until 1971, when a separate Legislative Building was constructed south of the Capitol.  The Legislative Building was expanded in 1997 to its current appearance to accommodate the growing Legislature. The Nevada Assembly is the lower house of the Nevada Legislature, the state legislature of the US state of Nevada.  The body consists of 42 members, elected to two-year terms from single-member districts.  Each Assembly district contained approximately 64,299 people as of the 2010 census.  Term limits, limiting assembly members to six 2-year terms (12 years), took effect in 2010.  Twelve members of the Assembly were termed out with the 2010 election serving their last legislative session in 2011. The Nevada Revised Statutes (NRS) are all the current codified laws of the State of Nevada.  Nevada law consists of the Constitution of Nevada (the state constitution) and Nevada Revised Statutes.  The Nevada Supreme Court interprets the law and constitution of Nevada.  The Statutes of Nevada are a compilation of all legislation passed by the Nevada Legislature during a particular Legislative Session.  The Nevada Administrative Code (NAC) is the codified, administrative regulations of the Executive Branch.  The Nevada Register is a compilation of proposed, adopted, emergency and temporary administrative regulations, notices of intent and informational statements.  Nevada Supreme Court Opinions are the written decisions of the Nevada Supreme Court. Nevada's original State Routes were developed beginning in 1917 upon the creation of the Nevada Department of Highways.  Route numbers were not assigned according to any particular numbering system, and sequential numbers were often scattered throughout the state.  For example, while State Routes 27 and 28 were designated along highways near Lake Tahoe in northwestern Nevada, State Route 29 connected to Death Valley in central Nevada and State Route 30 was connected to Utah in northeastern Nevada.  Additionally, several suffixed highways, branching from the original parent route, were also designated.  The numbering of state routes was designated in state laws by the Nevada Legislature (codified in the Nevada Revised Statutes in later years); this had the side effect of many routes not being fully owned or maintained by the state. The Governor of Nevada is the chief magistrate of the U.S. state of Nevada, the head of the executive department of Nevada's state government and the commander-in-chief of the state's military forces.  The governor has a duty to enforce state laws, and the power to either approve or veto bills passed by the Nevada Legislature, to convene the legislature at any time, and, except in cases of treason or impeachment, to grant pardons and reprieves. Patricia Ann "Pat" Spearman (born in 1955) is an American cleric, veteran, and Democratic politician from North Las Vegas, Nevada.  She was elected in November 2012 to the Nevada Senate representing District 1, that is composed of the northern section of North Las Vegas and slivers of neighboring jurisdictions, after defeating incumbent John Jay Lee in the primary, and winning the general election.  Spearman became the first openly lesbian member of the Nevada Legislature.  She was re-elected in November 2016, and serves as co-majority whip since.  Regarded as one of the most liberal members of the Nevada Senate, Spearman has introduced bills that provide equal pay for women, support LGBT rights, and support veterans.  Moreover, she was involved in the process of establishing the Nevada Revenue Plan during the 2015 session. The Nevada Legislature is the state legislature of the U.S. state of Nevada.  The Legislature is a bicameral body, consisting of the lower house Nevada Assembly, with 42 members, and the upper house Nevada Senate, with 21 members.  All 63 members of the Legislature are elected from an equal amount of constituent districts across the state.  The Legislature is the third smallest bicameral state legislature in the United States (the Alaska Legislature is the smallest bicameral, with only 60 members and the Delaware General Assembly has 62 members). Olivia Diaz (born 1978 in Las Vegas, Nevada), is an American politician and a Democratic member of the Nevada Assembly since February 7, 2011 representing District 11.  Diaz is a member of the National Hispanic Caucus of State Legislators.
