Note: The word 'faster' was provided in the image under the 'Comparative' column. However, it does not appear in any of the sentences numbered 1 through 8. If it was intended to be related to one of the sentences, further clarification would be needed. Based solely on the provided sentences, 'stupid', 'nervous', and 'tired' are the adjectives that fit the description of being 'hidden' within the context of comparative/superlative forms (though they are presented here as base adjectives in the sentences, and the exercise implies finding comparative/superlative forms of *other* adjectives within the sentences if they exist).
