In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[EX Q]: Countries that are located in a region opposite to the Western side of said region are given which descriptor?, Context: Within a population, it is common for different ages and/or sexes to have different patterns of timing and distance. Female chaffinches Fringilla coelebs in Eastern Fennoscandia migrate earlier in the autumn than males do.
[EX A]: Eastern

[EX Q]: Who found that physical action cannot take on an arbitrary value?, Context: Classical statistical mechanics requires the existence of h (but does not define its value). Eventually, following upon Planck's discovery, it was recognized that physical action cannot take on an arbitrary value. Instead, it must be some multiple of a very small quantity, the "quantum of action", now called the Planck constant. Classical physics cannot explain this fact. In many cases, such as for monochromatic light or for atoms, this quantum of action also implies that only certain energy levels are allowed, and values in between are forbidden.
[EX A]: Planck

[EX Q]: Characters convey?, Context: The total number of Chinese characters from past to present remains unknowable because new ones are developed all the time – for instance, brands may create new characters when none of the existing ones allow for the intended meaning. Chinese characters are theoretically an open set and anyone can create new characters, though such inventions are rarely included in official character sets. The number of entries in major Chinese dictionaries is the best means of estimating the historical growth of character inventory.
[EX A]:
meaning
