Input: The Blitz
Airborne Interception radar (AI) was unreliable. The heavy fighting in the Battle of Britain had eaten up most of Fighter Command's resources, so there was little investment in night fighting. Bombers were flown with airborne search lights out of desperation[citation needed], but to little avail. Of greater potential was the GL (Gunlaying) radar and searchlights with fighter direction from RAF fighter control rooms to begin a GCI system (Ground Control-led Interception) under Group-level control (No. 10 Group RAF, No. 11 Group RAF and No. 12 Group RAF).

What was considered unreliable?
Output: Airborne Interception radar

Input: Electric motor
These motors were originally invented to drive the capstan(s) of magnetic tape drives in the burgeoning computer industry, where minimal time to reach operating speed and minimal stopping distance were critical. Pancake motors are still widely used in high-performance servo-controlled systems, robotic systems, industrial automation and medical devices. Due to the variety of constructions now available, the technology is used in applications from high temperature military to low cost pump and basic servos.

What type of servo-controlled systems use pancake motors?
Output: high-performance

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 makes it difficult to determine if someone is homosexual or not?
Output: individuals classified as homosexual in one study might not be identified the same way in another depending on which components are assessed

Input: Iran
Following the fracture of the Mongol Empire in 1256, Hulagu Khan, grandson of Genghis Khan, established the Ilkhanate in Iran. In 1370, yet another conqueror, Timur, followed the example of Hulagu, establishing the Timurid Empire which lasted for another 156 years. In 1387, Timur ordered the complete massacre of Isfahan, reportedly killing 70,000 citizens. The Ilkhans and the Timurids soon came to adopt the ways and customs of the Iranians, choosing to surround themselves with a culture that was distinctively Iranian.

Who established an Ilkhanate in Iran after the break up of the Mongol Empire in 1256?
Output:
Hulagu Khan
