When choosing what quotations to apply to an argument, it is important to consider what is directly relevant. For example, if the question asks about the effect of a character's appearance on the reader, it would be irrelevant to include a quotation about what the character had been doing that day. Another vital point is not to include quotations that are too lenghty; it takes away from the argument and takes up valuable word space. When embedding a quotation within a sentence, the key is to imagine that the quotation is part of the sentence itself. For example: The lady is described as having 'a gentle expression'.
