Input: Question: What is the scientific name of the flowers solitary bees often visit? Passage 1:LCD Soundsystem released "Call the Police" and "American Dream" together as a digital double-A-side single on May 5, 2017, acting as the lead single from the album. The two songs were made available for listening once midnight was reached in one's time zone. The band promoted the songs by performing both during the May 6 episode of the 42nd season of Saturday Night Live. On August 4, the band rolled out an ice cream truck outside of the Lollapalooza festival in Chicago promoting the album. The truck played songs from the album in the form of ice cream jingles through its speaker. A Twitter account for the truck was also launched to provide updates on where its current location was. On August 16, "Tonite" was premiered on Zane Lowe's radio show on Beats 1. Along with the premiere was the release of a music video for the track, directed by Joel Kefali. It was also subsequently made available for streaming on Spotify. A virtual reality experience made to accompany the song, titled "Dance Tonite", was released to the public on August 22, though first previewed privately in June. Available to use in an Internet browser, the experience allowed people with room scale virtual reality kits, such as the Oculus Rift, to dance along to the track. Those with more simpler VR headsets, like the Daydream View, could view the experience as well the dance performances done by others. The band teamed up with the Puckney and Moniker design studios from Amsterdam for the project, alongside Google's data arts team. On August 31, the band released a 14-minute instrumental track called "Pulse (v.1)" as a free download. On Facebook, Murphy wrote that the track was "not precisely part of the record," but instead thought of it as an "addendum" meant to be played after the album's closing track, "Black Screen". It was originally left off of American Dream due to it not being able to fit on the vinyl format of the album. A music video for "Oh Baby", directed by Rian Johnson, was released on September 20, 2018. The video depicts an elderly couple, portrayed by Sissy Spacek and David Strathairn, who build a teleporter in their garage.
 Passage 2:Asante began his senior career in England with Birmingham City. He made his first-team debut in the Europa League play-off round second leg against C.D. Nacional in August 2011, and made his debut in the Football League while on loan at Northampton Town in January 2012. He had spells on loan at Shrewsbury Town in both 2012–13 and 2013–14, but injury disrupted his progress, and he left Birmingham when his contract expired. Without a club while recovering from injury, he spent the latter part of the 2014–15 season with Kidderminster Harriers before moving on to Solihull Moors, with whom he won the National League North title. Asante signed for Grimsby Town in January 2017, after missing the first couple of months of 2017–18 recovering from injury, he went on loan to Solihull Moors, however, he left Grimsby by mutual consent in February 2018. He completed the season with Tamworth, and after a short spell on loan at Chester, he joined them permanently in January 2019.
 Passage 3:Anemophilous pollen grains are light and non-sticky, so that they can be transported by air currents. They are typically in diameter, although the pollen grains of Pinus species can be much larger and much less dense. Anemophilous plants possess well-exposed stamens so that the pollens are exposed to wind currents and also have large and feathery stigma to easily trap airborne pollen grains. Pollen from anemophilous plants tends to be smaller and lighter than pollen from entomophilous ones, with very low nutritional value to insects. However, insects sometimes gather pollen from staminate anemophilous flowers at times when higher-protein pollens from entomophilous flowers are scarce. Anemophilous pollens may also be inadvertently captured by bees' electrostatic field. This may explain why, though bees are not observed to visit ragweed flowers, its pollen is often found in honey made during the ragweed floral bloom. Other flowers that are generally anemophilous are observed to be actively worked by bees, with solitary bees often visiting grass flowers, and the larger honeybees and bumblebees frequently gathering pollen from corn tassels and other grains.
