Question: Who was the manager for the Kansas City Royals when Travis hit two home runs against them? Passage:In late April 2016, Travis began taking part in extended spring training games. He was assigned to the Advanced-A Dunedin Blue Jays for rehab on May 13. On May 18, he was promoted to the Triple-A Buffalo Bisons to continue rehabbing. On May 25, Travis was activated off the disabled list by the Blue Jays and called up. He hit a walk-off infield single on May 28 to help the Blue Jays defeat the Boston Red Sox 10–9. On August 5, Travis hit two home runs in a game for the first time in his career. Leading off against the Kansas City Royals, Travis hit a solo home run to give the Blue Jays an early 1–0 lead. In the ninth inning, he hit another solo home run off Kelvin Herrera to lift Toronto to a 4–3 victory. On August 8, Travis hit his first career triple, which came as part of a four-hit game against the Tampa Bay Rays. Following a game on August 31, the Blue Jays optioned Travis to the Rookie-Advanced Bluefield Blue Jays. The move was made to allow Josh Thole to be re-signed and have postseason eligibility. As the Bluefield season would end on September 1, Travis could be immediately recalled by Toronto afterward, bypassing the ten-day waiting period. Travis was recalled by the Blue Jays on September 2. He finished the season hitting .300 with 11 home runs and 50 RBI in 101 games. Travis played in the Wild Card Game and the first game of the American League Division Series, but missed the remainder of the ALDS with a bone bruise in his right knee. He played in the first game of the Championship Series, but left in the fifth inning after reaggravating his knee injury. On October 15, Travis was removed from the ALCS roster due to injury, and replaced by Justin Smoak. In accordance with MLB rules, Travis was ruled ineligible to return for the postseason, ending his season. On November 18, he underwent right knee surgery to remove a small flap of cartilage, and was expected to be ready for spring training.

Question: Did other scientists keep blending inheritance open for further consideration? Passage:In the preface, Fisher considers some general points, including that there must be an understanding of natural selection distinct from that of evolution, and that the then-recent advances in the field of genetics (see history of genetics) now allowed this. In the first chapter, Fisher considers the nature of inheritance, rejecting blending inheritance, because it would eliminate genetic variance, in favour of particulate inheritance. The second chapter introduces Fisher's fundamental theorem of natural selection. The third considers the evolution of dominance, which Fisher believed was strongly influenced by modifiers. Other chapters discuss parental investment, Fisher's geometric model, concerning how spontaneous mutations affect biological fitness, Fisher's principle which explains why the sex ratio between males and females is almost always 1:1, reproductive value, examining the demography of having girl children. Using his knowledge of statistics, the Fisherian runaway, which explores how sexual selection can lead to a positive feedback runaway loop, producing features such as the peacock's plumage. He also wrote about the evolution of dominance, which explores genetic dominance. The last five chapters (8-12) include Fisher's more idiosyncratic views on eugenics.

Question: What is the lowest point of the place where Ndiku was born? Passage:Born in Machakos, he began running seriously around 2004 in the hope he could make a living out of the sport. Ndiku made his international debut at the 2007 World Youth Championships in Athletics, coming fourth in the 2000 metres steeplechase event. His technique was poor and his coach, Paul Mutwii, turned to Boniface Teren, the Kenyan national steeplechase coach, for help. Working with Teren, Ndiku's technique over the barriers greatly improved and one year later he won the gold medal at the 2008 World Junior Championships in Athletics, beating Uganda's Benjamin Kiplagat who had built up a sizeable lead in the early stages. Ndiku's winning time of 8:17.28 minutes was enough to rank the 16-year-old in the top 25 athletes in the world that year, as well as being the fastest ever recorded by a youth category athlete. His flat speed also improved, as he won the 1500 metres at the Commonwealth Youth Games that year. He also competed in Japan that year. After signing up with the Hitachi Cable corporate running team, he set track bests of 7:54.04 minutes for the 3000 metres, 13:21.17 minutes for the 5000 metres and 28:08.28 minutes for the 10,000 metres.
