Problem: Text: Wild wolves are sometimes kept as exotic pets, and in some rarer occasions, as working animals. Although closely related to domesticated dogs, wolves do not show the same tractability as dogs in living alongside humans, and generally, much more work is required in order to obtain the same amount of reliability. Wolves also need much more space than dogs, about 25 to 40 square kilometres (10 to 15 sq mi) so they can exercise.

Question: is it possible to have a wolf as a pet?
A: yes

Problem: Text: Regulation of the legal profession is a power reserved to the states pursuant to the Tenth Amendment to the US Constitution. Each state, territory and the District of Columbia has its own rules. Unlike many other countries, US jurisdictions do not license legal practitioners as solicitors and barristers, but all licensed attorneys are qualified to practice as both.

Question: can an attorney practice law in any state?
A: no

Problem: Text: Some non-benzene-based compounds called heteroarenes, which follow Huckel's rule (for monocyclic rings: when the number of its electrons equals 4n + 2, where n = 0, 1, 2, 3, ...), are also called aromatic compounds. In these compounds, at least one carbon atom is replaced by one of the heteroatoms oxygen, nitrogen, or sulfur. Examples of non-benzene compounds with aromatic properties are furan, a heterocyclic compound with a five-membered ring that includes a single oxygen atom, and pyridine, a heterocyclic compound with a six-membered ring containing one nitrogen atom.

Question: do all aromatic compounds have a benzene ring?
A:
no
