Problem: Bacteria:

There are approximately ten times as many bacterial cells in the human flora as there are human cells in the body, with the largest number of the human flora being in the gut flora, and a large number on the skin. The vast majority of the bacteria in the body are rendered harmless by the protective effects of the immune system, and some are beneficial. However, several species of bacteria are pathogenic and cause infectious diseases, including cholera, syphilis, anthrax, leprosy, and bubonic plague. The most common fatal bacterial diseases are respiratory infections, with tuberculosis alone killing about 2 million people per year, mostly in sub-Saharan Africa. In developed countries, antibiotics are used to treat bacterial infections and are also used in farming, making antibiotic resistance a growing problem. In industry, bacteria are important in sewage treatment and the breakdown of oil spills, the production of cheese and yogurt through fermentation, and the recovery of gold, palladium, copper and other metals in the mining sector, as well as in biotechnology, and the manufacture of antibiotics and other chemicals.

What are the deadliest diseases caused by bacteria?

A: respiratory infections

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Some Western writers claim that the immaculate conception of Mary is a teaching of Islam. Thus, commenting in 1734 on the passage in the Qur'an, "I have called her Mary; and I commend her to thy protection, and also her issue, against Satan driven away with stones", George Sale stated: "It is not improbable that the pretended immaculate conception of the virgin Mary is intimated in this passage. For according to a tradition of Mohammed, every person that comes into the world, is touched at his birth by the devil, and therefore cries out, Mary and her son only excepted; between whom, and the evil spirit God placed a veil, so that his touch did not reach them. And for this reason they say, neither of them were guilty of any sin, like the rest of the children of Adam."
What does the Qur'an say is pretended?
A: unanswerable


Context and question: The Pamiri people of Gorno-Badakhshan Autonomous Province in the southeast, bordering Afghanistan and China, though considered part of the Tajik ethnicity, nevertheless are distinct linguistically and culturally from most Tajiks.

Isolated in the highest parts of the Pamir Mountains, they have preserved many ancient cultural traditions and folk arts that have been largely lost elsewhere in the country.
What people are not distinct linguistically and culturally from most Tajiks?
