The test for Grades 9-12 covers biology, chemistry, and physics, with 20 questions in each general field (though physics and chemistry often overlap). Each school may send up to three students for each junior high division. In order for a school to participate in team competition, the school must send three students.
Mathematically, if each question is structured to eliminate half the objects, 20 questions allow the questioner to distinguish between 2 20 = 1 048 576 objects. Accordingly, the most effective strategy for twenty questions is to ask questions that will split the field of remaining possibilities roughly in half each time.
In 2020, it was announced that Google's AlphaFold, a neural network based on DeepMind artificial intelligence, is capable of predicting a protein's final shape based solely on its amino-acid chain with an accuracy of around 90% on a test sample of proteins used by the team. [16]
20Q is a computerized game of twenty questions that began as a test in artificial intelligence (AI). It was invented by Robin Burgener in 1988. [1] The game was made handheld by Radica in 2003, but was discontinued in 2011 because Techno Source took the license for 20Q handheld devices.
The United States National Chemistry Olympiad (or USNCO) is a contest held by the American Chemical Society (ACS) used to select the four-student team that represents the United States at the International Chemistry Olympiad (IChO). Each local ACS section selects 10 students (or more for larger ACS sections) to take the USNCO National Exam.
The next 15 questions, numbered 101-115, were called 'relationship analysis questions'.

Twenty Questions, based on the guessing game Twenty questions, started as a radio quiz show in 1946. The television series ran on NBC in 1949, on ABC from 1950 to 1951 and on the DuMont Television Network from 1951 to 1954.
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
