Problem: Catalan language:

Catalan dialects are relatively uniform, and are mutually intelligible. They are divided into two blocks, Eastern and Western, differing mostly in pronunciation. The terms "Catalan" and "Valencian" (respectively used in Catalonia and the Valencian Community) are two different varieties of the same language. There are two institutions regulating the two standard varieties, the Institute of Catalan Studies in Catalonia and the Valencian Academy of the Language in Valencia.

What is the basic difference between the dialects?
---
A: pronunciation

Problem: Greece:

The principal gods of the ancient Greek religion were the Dodekatheon, or the Twelve Gods, who lived on the top of Mount Olympus. The most important of all ancient Greek gods was Zeus, the king of the gods, who was married to Hera, who was also Zeus's sister. The other Greek gods that made up the Twelve Olympians were Demeter, Ares, Poseidon, Athena, Dionysus, Apollo, Artemis, Aphrodite, Hephaestus and Hermes. Apart from these twelve gods, Greeks also had a variety of other mystical beliefs, such as nymphs and other magical creatures.

Problem: United Nations Population Fund:

UNFPA has been falsely accused by anti-family planning groups of providing support for government programs which have promoted forced-abortions and coercive sterilizations. Controversies regarding these claims have resulted in a sometimes shaky relationship between the organization and three presidential administrations, that of Ronald Reagan, George H. W. Bush and George W. Bush, withholding funding from the UNFPA.

What groups have dismissed these accusations against UNFPA?
---
A: unanswerable

Problem: Dog:

In Islam, dogs are viewed as unclean because they are viewed as scavengers. In 2015 city councillor Hasan Kucuk of The Hague called for dog ownership to be made illegal in that city. Islamic activists in Lerida, Spain, lobbied for dogs to be kept out of Muslim neighborhoods, saying their presence violated Muslims' religious freedom. In Britain, police sniffer dogs are carefully used, and are not permitted to contact passengers, only their luggage. They are required to wear leather dog booties when searching mosques or Muslim homes.

What are sniffer dogs used by British police allowed to touch instead of a passenger?
---

their luggage
