Problem: Gene:

Defining exactly what section of a DNA sequence comprises a gene is difficult. Regulatory regions of a gene such as enhancers do not necessarily have to be close to the coding sequence on the linear molecule because the intervening DNA can be looped out to bring the gene and its regulatory region into proximity. Similarly, a gene's introns can be much larger than its exons. Regulatory regions can even be on entirely different chromosomes and operate in trans to allow regulatory regions on one chromosome to come in contact with target genes on another chromosome.

Why do some regulatory regions of a gene not have to be close to the coding sequence?
---
A: because the intervening DNA can be looped out to bring the gene and its regulatory region into proximity

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Application of electric motors revolutionized industry. Industrial processes were no longer limited by power transmission using line shafts, belts, compressed air or hydraulic pressure. Instead every machine could be equipped with its own electric motor, providing easy control at the point of use, and improving power transmission efficiency. Electric motors applied in agriculture eliminated human and animal muscle power from such tasks as handling grain or pumping water. Household uses of electric motors reduced heavy labor in the home and made higher standards of convenience, comfort and safety possible. Today, electric motors stand for more than half of the electric energy consumption in the US.
In what domain did electric motors reduce reliance on humans and animals?
A: agriculture

Context and question: Draught beer's environmental impact can be 68% lower than bottled beer due to packaging differences. A life cycle study of one beer brand, including grain production, brewing, bottling, distribution and waste management, shows that the CO2 emissions from a 6-pack of micro-brew beer is about 3 kilograms (6.6 pounds). The loss of natural habitat potential from the 6-pack of micro-brew beer is estimated to be 2.5 square meters (26 square feet). Downstream emissions from distribution, retail, storage and disposal of waste can be over 45% of a bottled micro-brew beer's CO2 emissions. Where legal, the use of a refillable jug, reusable bottle or other reusable containers to transport draught beer from a store or a bar, rather than buying pre-bottled beer, can reduce the environmental impact of beer consumption.
What beer is better for the environment than bottled beer?
Answer: Draught beer's

Question: After a death sentence is affirmed in state collateral review, the prisoner may file for federal habeas corpus, which is a unique type of lawsuit that can be brought in federal courts. Federal habeas corpus is a species of collateral review, and it is the only way that state prisoners may attack a death sentence in federal court (other than petitions for certiorari to the United States Supreme Court after both direct review and state collateral review). The scope of federal habeas corpus is governed by the Antiterrorism and Effective Death Penalty Act of 1996, which restricted significantly its previous scope. The purpose of federal habeas corpus is to ensure that state courts, through the process of direct review and state collateral review, have done at least a reasonable job in protecting the prisoner's federal constitutional rights. Prisoners may also use federal habeas corpus suits to bring forth new evidence that they are innocent of the crime, though to be a valid defense at this late stage in the process, evidence of innocence must be truly compelling.
Is there an answer to this question: If prisoners use federal habeas corpus to present evidence that they're innocent, what must the evidence be?

Answer: truly compelling

Problem: John, King of England:

John was deeply suspicious of the barons, particularly those with sufficient power and wealth to potentially challenge the king. Numerous barons were subjected to John's malevolentia, even including William Marshal, a famous knight and baron normally held up as a model of utter loyalty. The most infamous case, which went beyond anything considered acceptable at the time, proved to be that of William de Braose, a powerful marcher lord with lands in Ireland. De Braose was subjected to punitive demands for money, and when he refused to pay a huge sum of 40,000 marks (equivalent to 26,666 at the time),[nb 13] his wife and one of his sons were imprisoned by John, which resulted in their deaths. De Braose died in exile in 1211, and his grandsons remained in prison until 1218. John's suspicions and jealousies meant that he rarely enjoyed good relationships with even the leading loyalist barons.

John was deeply suspicious of who?
---
A:
the barons
