Problem: Dialect:

Italians in different regions today may also speak regional varieties of standard Italian, or regional Italian dialects, which, unlike the majority of languages of Italy, are actually dialects of standard Italian rather than separate languages. A regional Italian dialect is generally standard Italian that has been heavily influenced or mixed with local or regional native languages and accents.

Regional Italian dialects are often influenced by regional languages and what other language?
---
A: standard Italian

Problem: There are more than 100 freshwater fish species, varying from the giant European catfish (in the Tagus International Natural Park) to some small and endemic species that live only in small lakes (along the western portion of country, for example). Some of these rare and specific species are highly endangered because of habitat loss, pollution and drought. Up-welling along the west coast of Portugal makes the sea extremely rich in nutrients and diverse species of marine fish; the Portuguese marine waters are one of the richest in the world. Marine fish species are more common, and include thousands of species, such as the sardine (Sardina pilchardus), tuna and Atlantic mackerel. Bioluminescent species are also well represented (including species in different colour spectrum and forms), like the glowing plankton that are possible to observe in some beaches.
What type of glowing species can be found on some beaches in Portugal?
---
Answer: plankton

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Jehovah's Witnesses believe that God's kingdom is a literal government in heaven, ruled by Jesus Christ and 144,000 "spirit-anointed" Christians drawn from the earth, which they associate with Jesus' reference to a "new covenant". The kingdom is viewed as the means by which God will accomplish his original purpose for the earth, transforming it into a paradise without sickness or death. It is said to have been the focal point of Jesus' ministry on earth. They believe the kingdom was established in heaven in 1914, and that Jehovah's Witnesses serve as representatives of the kingdom on earth.
How many Jehovah's Witnesses are there now?
A: unanswerable

Context and question: In 1998 the Angiosperm Phylogeny Group published a phylogeny for flowering plants based on an analysis of DNA sequences from most families of flowering plants. As a result of this work, many questions, such as which families represent the earliest branches of angiosperms, have now been answered. Investigating how plant species are related to each other allows botanists to better understand the process of evolution in plants. Despite the study of model plants and increasing use of DNA evidence, there is ongoing work and discussion among taxonomists about how best to classify plants into various taxa. Technological developments such as computers and electron microscopes have greatly increased the level of detail studied and speed at which data can be analysed.
What have scientists learned about angiosperms from DNA sequencing?
Answer: which families represent the earliest branches

Question: As of November 2008, there is only one person on death row facing capital punishment who has not been convicted of murder. Demarcus Sears remains under a death sentence in Georgia for the crime of "kidnapping with bodily injury." Sears was convicted in 1986 for the kidnapping and bodily injury of victim Gloria Ann Wilbur. Wilbur was kidnapped and beaten in Georgia, raped in Tennessee, and murdered in Kentucky. Sears was never charged with the murder of Wilbur in Kentucky, but was sentenced to death by a jury in Georgia for "kidnapping with bodily injury."
Is there an answer to this question: In what state was Gloria Ann Wilbur born?

Answer: unanswerable

Problem: Electric motor:

Because the rotor is much lighter in weight (mass) than a conventional rotor formed from copper windings on steel laminations, the rotor can accelerate much more rapidly, often achieving a mechanical time constant under one ms. This is especially true if the windings use aluminum rather than the heavier copper. But because there is no metal mass in the rotor to act as a heat sink, even small coreless motors must often be cooled by forced air. Overheating might be an issue for coreless DC motor designs.

What advantage does a coreless rotor have over traditional variants?
---
A:
accelerate much more rapidly
