Problem: Dialect:

Another occasionally used criterion for discriminating dialects from languages is that of linguistic authority, a more sociolinguistic notion. According to this definition, two varieties are considered dialects of the same language if (under at least some circumstances) they would defer to the same authority regarding some questions about their language. For instance, to learn the name of a new invention, or an obscure foreign species of plant, speakers of Bavarian German and East Franconian German might each consult a German dictionary or ask a German-speaking expert in the subject. By way of contrast, although Yiddish is classified by linguists as a language in the "Middle High German" group of languages, a Yiddish speaker would not consult a German dictionary to determine the word to use in such a case.

Which language is classified by linguists as being in the Lower High German group?

A: unanswerable

Problem: Ground Control is responsible for directing all ground traffic in designated "movement areas", except the traffic on runways. This includes planes, baggage trains, snowplows, grass cutters, fuel trucks, stair trucks, airline food trucks, conveyor belt vehicles and other vehicles. Ground Control will instruct these vehicles on which taxiways to use, which runway they will use (in the case of planes), where they will park, and when it is safe to cross runways. When a plane is ready to takeoff it will stop short of the runway, at which point it will be turned over to Tower Control. After a plane has landed, it will depart the runway and be returned to Ground Control.
Who instructs vehicles on which taxiways to use?

Answer: Ground Control

Context and question: This view is supported by a study of the region where these notions originated. Buddhism arose in Greater Magadha, which stretched from Sravasti, the capital of Kosala in the north-west, to Rajagrha in the south east. This land, to the east of aryavarta, the land of the Aryas, was recognized as non-Vedic. Other Vedic texts reveal a dislike of the people of Magadha, in all probability because the Magadhas at this time were not Brahmanised.[page needed] It was not until the 2nd or 3rd centuries BCE that the eastward spread of Brahmanism into Greater Magadha became significant. Ideas that developed in Greater Magadha prior to this were not subject to Vedic influence. These include rebirth and karmic retribution that appear in a number of movements in Greater Magadha, including Buddhism. These movements inherited notions of rebirth and karmic retribution from an earlier culture[page needed]
Greater magadha stretched from Sravasti in the north-west to what area in the south-east?
Answer: Rajagrha

Question: In 2002, the Musharraf-led government took a firm stand against the jihadi organizations and groups promoting extremism, and arrested Maulana Masood Azhar, head of the Jaish-e-Mohammed, and Hafiz Muhammad Saeed, chief of the Lashkar-e-Taiba, and took dozens of activists into custody. An official ban was imposed on the groups on 12 January. Later that year, the Saudi born Zayn al-Abidn Muhammed Hasayn Abu Zubaydah was arrested by Pakistani officials during a series of joint U.S.-Pakistan raids. Zubaydah is said to have been a high-ranking al-Qaeda official with the title of operations chief and in charge of running al-Qaeda training camps. Other prominent al-Qaeda members were arrested in the following two years, namely Ramzi bin al-Shibh, who is known to have been a financial backer of al-Qaeda operations, and Khalid Sheikh Mohammed, who at the time of his capture was the third highest-ranking official in al-Qaeda and had been directly in charge of the planning for the 11 September attacks.
Is there an answer to this question: What was the rank of Ramzi bin al-Shibh?

Answer: unanswerable

Problem: Biodiversity:

Finally, an introduced species may unintentionally injure a species that depends on the species it replaces. In Belgium, Prunus spinosa from Eastern Europe leafs much sooner than its West European counterparts, disrupting the feeding habits of the Thecla betulae butterfly (which feeds on the leaves). Introducing new species often leaves endemic and other local species unable to compete with the exotic species and unable to survive. The exotic organisms may be predators, parasites, or may simply outcompete indigenous species for nutrients, water and light.

What animal can its feeding habits disturbed by the Prunus spinosa?
---
A:
leaves endemic and other local species unable to compete with the exotic species and unable to survive
