Problem: Baptists:

Many Baptist churches choose to affiliate with organizational groups that provide fellowship without control. The largest such group is the Southern Baptist Convention. There also are a substantial number of smaller cooperative groups. Finally, there are Baptist churches that choose to remain autonomous and independent of any denomination, organization, or association. It has been suggested that a primary Baptist principle is that local Baptist Churches are independent and self-governing, and if so the term 'Baptist denomination' may be considered somewhat incongruous.

What term is not considered to be incongruous?

A: unanswerable

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The first high-brightness blue LED was demonstrated by Shuji Nakamura of Nichia Corporation in 1994 and was based on InGaN. In parallel, Isamu Akasaki and Hiroshi Amano in Nagoya were working on developing the important GaN nucleation on sapphire substrates and the demonstration of p-type doping of GaN. Nakamura, Akasaki and Amano were awarded the 2014 Nobel prize in physics for their work. In 1995, Alberto Barbieri at the Cardiff University Laboratory (GB) investigated the efficiency and reliability of high-brightness LEDs and demonstrated a "transparent contact" LED using indium tin oxide (ITO) on (AlGaInP/GaAs).
What color non-LED was demonstrated in 1994?
A: unanswerable

Context and question: Honorary knighthoods are appointed to citizens of nations where Queen Elizabeth II is not Head of State, and may permit use of post-nominal letters but not the title of Sir or Dame. Occasionally honorary appointees are, incorrectly, referred to as Sir or Dame - Bill Gates or Bob Geldof, for example. Honorary appointees who later become a citizen of a Commonwealth realm can convert their appointment from honorary to substantive, then enjoy all privileges of membership of the order including use of the title of Sir and Dame for the senior two ranks of the Order. An example is Irish broadcaster Terry Wogan, who was appointed an honorary Knight Commander of the Order in 2005 and on successful application for dual British and Irish citizenship was made a substantive member and subsequently styled as "Sir Terry Wogan KBE".
What is an example of irish broadcaster?
Answer: Terry Wogan

Question: Antibiotics revolutionized medicine in the 20th century, and have together with vaccination led to the near eradication of diseases such as tuberculosis in the developed world. Their effectiveness and easy access led to overuse, especially in livestock raising, prompting bacteria to develop resistance. This has led to widespread problems with antimicrobial and antibiotic resistance, so much as to prompt the World Health Organization to classify antimicrobial resistance as a "serious threat [that] is no longer a prediction for the future, it is happening right now in every region of the world and has the potential to affect anyone, of any age, in any country".
Is there an answer to this question: What can be affected by issues resulting from overuse of antibiotics?

Answer: anyone, of any age, in any country
