A closed-ended question is any question for which a researcher provides research participants with options from which to choose a response. [1] Closed-ended questions are sometimes phrased as a statement that requires a response. A closed-ended question contrasts with an open-ended question, which cannot easily be answered with specific ...
An example of such a question is "What did Albert Einstein win the Nobel Prize for?" after an article about this subject is given to the system. Closed-book question answering is when a system has memorized some facts during training and can answer questions without explicitly being given a context. This is similar to humans taking closed-book ...
The verifier-based definition of NP does not require an efficient verifier for the "no"-answers. The class of problems with such verifiers for the "no"-answers is called co-NP. In fact, it is an open question whether all problems in NP also have verifiers for the "no"-answers and thus are in co-NP.
Two notable examples in mathematics that have been solved and closed by researchers in the late twentieth century are Fermat's Last Theorem [1] and the four-color theorem. [ 2 ] [ 3 ] An important open mathematics problem solved in the early 21st century is the Poincaré conjecture .
In linguistics, a yes–no question, also known as a binary question, a polar question, or a general question, [1] or closed-ended question is a question whose expected answer is one of two choices, one that provides an affirmative answer to the question versus one that provides a negative answer to the question.
A closed system is a natural physical system that does not allow transfer of matter in or out of the system, although – in the contexts of physics, chemistry, engineering, etc. – the transfer of energy (e.g. as work or heat) is allowed.
[3] [4] Display questions bear similarities to closed questions in terms of their requirement for short and limited answers and they can be classified under convergent questions. On the other hand, referential questions and open questions are similar in their requirement for long, often varied, answers, and can be grouped under divergent questions.
A leading question is a question that suggests a particular answer and contains information the examiner is looking to have confirmed. [1] The use of leading questions in court to elicit testimony is restricted in order to reduce the ability of the examiner to direct or influence the evidence presented. Depending on the circumstances, leading ...
