Background: Theodore John Kaczynski (; born May 22, 1942), also known as the Unabomber, is an American domestic terrorist. A mathematics prodigy, he abandoned an academic career in 1969 to pursue a primitive lifestyle, then between 1978 and 1995 he killed three people, and injured 23 others, in a nationwide bombing campaign targeting those involved with modern technology. In conjunction, he issued a social critique opposing industrialization and advancing a nature-centered form of anarchism.
Context: At Harvard, Kaczynski lived during his first year at 8 Prescott Street, which was designed to accommodate the youngest, most precocious freshmen in a small, intimate living space. The next three years he lived at Eliot House. One of his suitemates there recalled that he avoided contact with others and "would just rush through the suite, go into his room, and slam the door." Another suitemate said Kaczynski was reserved, but regarded him as a genius: "It's just an opinion - but Ted was brilliant." Other students stated Kaczynski was less socially averse than these descriptions imply; an Eliot House resident who dined with Kaczynski at times called him "very quiet, but personable ... He would enter into the discussions maybe a little less so than most [but] he was certainly friendly."  As a sophomore, Kaczynski participated in a study described by author Alton Chase as a "purposely brutalizing psychological experiment", led by Harvard psychologist Henry Murray. Subjects were told they would be debating personal philosophy with a fellow student, and were asked to write essays detailing their personal beliefs and aspirations. The essays were turned over to an anonymous attorney, who in a later session would confront and belittle the subject - making "vehement, sweeping, and personally abusive" attacks - using the content of the essays as ammunition, while electrodes monitored the subject's physiological reactions. These encounters were filmed, and subjects' expressions of rage were later played back to them repeatedly. The experiment ultimately lasted three years, with someone verbally abusing and humiliating Kaczynski each week. In total, Kaczynski spent 200 hours as part of the study. Kaczynski's lawyers later attributed his hostility towards mind control techniques to this experience. Some sources have suggested that Murray's experiments were part of the US government's research into mind control, known as Project MKUltra. Chase and others have also suggested that this experience may have motivated Kaczynski's criminal activities, while philosopher Jonathan D. Moreno has said that, while "Kaczynski's anti-technological fixation and his critique itself had some roots in the Harvard curriculum," Kaczynski's later bombing campaign can "by no means be laid at Harvard's door".  Kaczynski earned his Bachelor of Arts degree in mathematics from Harvard in 1962. He finished with an above-average 3.12 GPA but had been expected to perform better.
Question: How did he react to the experiment?
Answer: Kaczynski's lawyers later attributed his hostility towards mind control techniques to this experience.

Problem: Background: The Houston Livestock Show and Rodeo, also called RodeoHouston or abbreviated HLSR, is the largest livestock exhibitions and rodeo in the world. It also includes one of the richest regular-season rodeo events. It has been held at NRG Stadium in Houston, Texas, since 2003. It was previously held in the Astrodome.
Context: Since 1952, traditional trail rides have been a part of the Houston Livestock Show and Rodeo. As of 2017, there were 13 official trail rides, totaling over 3,000 riders. The trail rides range in size from a dozen to over one thousand people who ride on horseback or in horse-drawn wagons from various areas of the state to Houston. They make their way at about 3 miles (4.8 km) per hour, covering up to 17 miles (27 km) each day. Many of the routes take place in part along major highways and busy city streets, making safety a major concern.  The trail rides last from a few days to three weeks, depending on the distance they cover. Some of the participants are able to join only on weekends or at the end of the trip. The days start very early, and often end with live music or a small celebration. Many riders choose to camp in recreational vehicles rather than in the open. Each morning, they drive their vehicles and horse trailers to the next camping spot, then have a bus or convoy take them back so they can retrace their path on horseback. Participants can bring their own provisions, or, in some cases, purchase meals at a chuck wagon that is also following the trail.  The rides converge at Memorial Park in Houston on Go Texan Day, the Friday before the livestock show and rodeo begins. The city closes some roads downtown to allow the riders to reach their destination safely. The resulting traffic interruption cause annual complaints from those who work downtown. The following day, all of the trail riders participate in the parade.
Question: How far is the longest trail ride?
Answer:
They make their way at about 3 miles (4.8 km) per hour, covering up to 17 miles (27 km) each day.
