Problem: Flowering plant:

Animals are also involved in the distribution of seeds. Fruit, which is formed by the enlargement of flower parts, is frequently a seed-dispersal tool that attracts animals to eat or otherwise disturb it, incidentally scattering the seeds it contains (see frugivory). Although many such mutualistic relationships remain too fragile to survive competition and to spread widely, flowering proved to be an unusually effective means of reproduction, spreading (whatever its origin) to become the dominant form of land plant life.

What did mutualistic relationships spread to eventually become?

Problem: In May 2013, Thein Sein became the first Myanmar president to visit the White House in 47 years; the last Burmese leader to visit the White House was Ne Win in September 1966. President Barack Obama praised the former general for political and economic reforms, and the cessation of tensions between Myanmar and the United States. Political activists objected to the visit due to concerns over human rights abuses in Myanmar but Obama assured Thein Sein that Myanmar will receive US support. The two leaders discussed to release more political prisoners, the institutionalisation of political reform and rule of law, and ending ethnic conflict in Myanmarthe two governments agreed to sign a bilateral trade and investment framework agreement on 21 May 2013.
Was the visit from the Burmese delegate welcome in the United States in 2010?

In the early 20th century several mandolin orchestras (Estudiantinas) were active in Belgium. Today only a few groups remain: Royal Estudiantina la Napolitaine (founded in 1904) in Antwerp, Brasschaats mandoline orkest in Brasschaat and an orchestra in Mons (Bergen). Gerda Abts is a well known mandolin virtuoso in Belgium. She is also mandolin teacher and gives lessons in the music academies of Lier, Wijnegem and Brasschaat. She is now also professor mandolin at the music high school "Koninklijk Conservatorium Artesis Hogeschool Antwerpen". She also gives various concerts each year in different ensembles. She is in close contact to the Brasschaat mandolin Orchestra. Her site is www.gevoeligesnaar.be
Where is Gerda Abst a professor mandolin?

Context and question: Multiracial Americans are Americans who have mixed ancestry of "two or more races". The term may also include Americans of mixed-race ancestry who self-identify with just one group culturally and socially (cf. the one-drop rule). In the 2010 US census, approximately 9 million individuals, or 2.9% of the population, self-identified as multiracial. There is evidence that an accounting by genetic ancestry would produce a higher number, but people live according to social and cultural identities, not DNA. Historical reasons, including slavery creating a racial caste and the European-American suppression of Native Americans, often led people to identify or be classified by only one ethnicity, generally that of the culture in which they were raised. Prior to the mid-20th century, many people hid their multiracial heritage because of racial discrimination against minorities. While many Americans may be biologically multiracial, they often do not know it or do not identify so culturally, any more than they maintain all the differing traditions of a variety of national ancestries.
Approximentally how many Americans identified themselves as multiracial in the 2010 US census?
Answer: In the 2010 US census, approximately 9 million individuals, or 2.9% of the population, self-identified as multiracial.

Question: The standard PlayStation 3 version of the XrossMediaBar (pronounced Cross Media Bar, or abbreviated XMB) includes nine categories of options. These are: Users, Settings, Photo, Music, Video, TV/Video Services, Game, Network, PlayStation Network and Friends (similar to the PlayStation Portable media bar). TheTV/Video Services category is for services like Netflix and/or if PlayTV or torne is installed; the first category in this section is "My Channels", which lets users download various streaming services, including Sony's own streaming services Crackle and PlayStation Vue. By default, the What's New section of PlayStation Network is displayed when the system starts up. PS3 includes the ability to store various master and secondary user profiles, manage and explore photos with or without a musical slide show, play music and copy audio CD tracks to an attached data storage device, play movies and video files from the hard disk drive, an optical disc (Blu-ray Disc or DVD-Video) or an optional USB mass storage or Flash card, compatibility for a USB keyboard and mouse and a web browser supporting compatible-file download function. Additionally, UPnP media will appear in the respective audio/video/photo categories if a compatible media server or DLNA server is detected on the local network. The Friends menu allows mail with emoticon and attached picture features and video chat which requires an optional PlayStation Eye or EyeToy webcam. The Network menu allows online shopping through the PlayStation Store and connectivity to PlayStation Portable via Remote Play.
Is there an answer to this question: What menu would you use to set up a video chat?

Answer: Friends

In 1911 arsphenamine, the first synthetic anti-infective drug, was developed by Paul Ehrlich and chemist Alfred Bertheim of the Institute of Experimental Therapy in Berlin. The drug was given the commercial name Salvarsan. Ehrlich, noting both the general toxicity of arsenic and the selective absorption of certain dyes by bacteria, hypothesized that an arsenic-containing dye with similar selective absorption properties could be used to treat bacterial infections. Arsphenamine was prepared as part of a campaign to synthesize a series of such compounds, and found to exhibit partially selective toxicity. Arsphenamine proved to be the first effective treatment for syphilis, a disease which prior to that time was incurable and led inexorably to severe skin ulceration, neurological damage, and death.[citation needed]
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Bacterial infections could be treated with medicines containing what kind of dye?
Ah, so..
arsenic
