Designed to assess comprehension of written ambiguous and polysemous structures, this instrument is a series of written statements that include varying degrees and types of ambiguity. In the first part of the test students are asked to identify (from a choice of three) semantically acceptable paraphrases for an initial sentence. Then students must independently paraphrase in writing all of the meanings in the same set of sentences. In the final part of the test, students are asked to independently paraphrase nine sentences. Comprehension of a structure is demonstrated by two acceptable interpretations out of the three items testing each aspect of ambiguity.

The TRIP review, included here as an introduction to the instrument, describes the instrument's category (language), title, author, date, age range (ages 10-16), purpose, and physical characteristics.)
