Input: Computer
The tide-predicting machine invented by Sir William Thomson in 1872 was of great utility to navigation in shallow waters. It used a system of pulleys and wires to automatically calculate predicted tide levels for a set period at a particular location.

What did Sir William Thomson's tide-predicting machine use to function?
Output: system of pulleys and wires

Input: Sexual orientation
The variance in prevalence rates is reflected in people's inconsistent responses to the different components of sexual orientation within a study and the instability of their responses over time. Laumann et al., (1994) found that among U.S. adults 20% of those who would be considered homosexual on one component of orientation were homosexual on the other two dimensions and 70% responded in a way that was consistent with homosexuality on only one of the three dimensions. Furthermore, sexuality is fluid such that one's sexual orientation is not necessarily stable or consistent over time but is subject to change throughout life. Diamond (2003) found that over 7 years 2/3 of the women changed their sexual identity at least once, with many reporting that the label was not adequate in capturing the diversity of their sexual or romantic feelings. Furthermore, women who relinquished bisexual and lesbian identification did not relinquish same sex sexuality and acknowledged the possibility for future same sex attractions and/or behaviour. One woman stated "I'm mainly straight but I'm one of those people who, if the right circumstance came along, would change my viewpoint". Therefore, individuals classified as homosexual in one study might not be identified the same way in another depending on which components are assessed and when the assessment is made making it difficult to pin point who is homosexual and who is not and what the overall prevalence within a population may be.

What did Diamond find about the women?
Output: over 7 years 2/3 of the women changed their sexual identity at least once,

Input: Northwestern University
In Fall 2008, Northwestern opened a campus in Education City, Doha, Qatar, joining five other American universities: Carnegie Mellon University, Cornell University, Georgetown University, Texas A&M University, and Virginia Commonwealth University. Through the Medill School of Journalism and School of Communication, NU-Q offers bachelor's degrees in journalism and communication respectively. The Qatar Foundation for Education, Science and Community Development provided funding for construction and administrative costs as well as support to hire 50 to 60 faculty and staff, some of whom rotate between the Evanston and Qatar campuses. In February 2016, Northwestern reached an agreement with the Qatar Foundation to extend the operations of the NU-Q branch for an additional decade, through the 2027-2028 academic year.

Who provided the funding for the construction and administrative costs for NU-Q?
Output: The Qatar Foundation for Education, Science and Community Development

Input: Frédéric Chopin
During 1824–28 Chopin spent his vacations away from Warsaw, at a number of locales.[n 4] In 1824 and 1825, at Szafarnia, he was a guest of Dominik Dziewanowski, the father of a schoolmate.
