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.
In linguistics, an echo answer or echo response is a way of answering a polar question without using words for yes and no. The verb used in the question is simply echoed in the answer, negated if the answer has a negative truth-value. [1] For example: "Did you go to the cinema?" (or "Didn't you go to the cinema?") "I did not." or "I didn't go."
In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms.
Questions come in a number of varieties. For instance; Polar questions are those such as the English example "Is this a polar question?", which can be answered with "yes" or "no". Alternative questions such as "Is this a polar question, or an alternative question?" present a list of possibilities to choose from.
DMSO is widely used as an alternative to water because it has a lower dielectric constant than water, and is less polar and so dissolves non-polar, hydrophobic substances more easily. It has a measurable pK a range of about 1 to 30. Acetonitrile is less basic than DMSO, and, so, in general, acids are weaker and bases are stronger in this solvent.
A decision problem is a yes-or-no question on an infinite set of inputs. It is traditional to define the decision problem as the set of possible inputs together with the set of inputs for which the answer is yes. [1] These inputs can be natural numbers, but can also be values of some other kind, like binary strings or strings over some other ...
A simple list of yes or no questions may be just what is needed to spur on more conversation. These funny and deep questions are also great for getting to know your friends or even your partner ...
A: (Yes,) John ate beans. (No,) John didn't eat beans. *Yes. *No. [6] As seen in this example, simply answering "Yes" or "No" does not suffice as a response to the question. This question must be answered in the "A" or "not A" form. If this question was asked in the A-not-A pattern, its direct form would be "Did John eat or not eat the beans?".
