Ineed this what word/s in the following sentence/s should be said with expression in order to best convey mood and meaning? i could not believe that i failed the test. i studied so hard. a. could, believe c. test, hard b. not, so d. i, i

Considering that tone is the speaker´s attitude towards a certain situation and consequently it expresses a specific emotion (mood and meaning). In this case, we can infer that the person feels dissapointed, sad and perhaps a little bit upset. He or she would "say with expression" option C. test, hard. (In fact I would emphasize believe and test in the first sentence and hard in the second).

sorry answered wrong answer

there purpose is to entertain
