Tasks at this
level, like those in the previous levels, ask the reader to match on multiple
features of information, to cycle through documents, and to integrate
information; frequently however, these tasks require the reader to make higher
order inferences to arrive at the correct answer. Sometimes, conditional
information is present in the document, which must be taken into account by the
reader. Patterns and trends to be identified are more complex than Level 3, and
matches are made on multiple features. Distractors for both requested and given
information can be found in the same node as the answer.
