Question

wednesday: (1) tsunami is the japanese word for tidal waves. (2) generated by hurricanes or by earthquakes these waves can reach speeds of five hundred mph. (3) even more spectacular than its speed is their height. (4) the most highest recorded crest was 220 feet.

Explanation:

• Sentence (1): "Tsunami" is a Japanese word, so no error.
• Sentence (2): "Generated by..." is a dangling modifier. It should be "These waves, generated by hurricanes or by earthquakes, can reach speeds of five hundred mph."
• Sentence (3): "its" should be "their" to agree with "waves".
• Sentence (4): "most highest" is redundant. Use "highest".

Answer:

• Sentence (2) has a dangling modifier error.
• Sentence (3) has a pronoun - agreement error (its → their).
• Sentence (4) has a redundancy error (most highest → highest).
