Question

Accepted Answer

A. invited - didn't come

Here are the answers:

1. C - The sentence should be: "The two boys were playing loudly when their parents arrived home from work." (The verb tense should be consistent, so "arriving" should be "arrived".)

2. B - The sentence should be: "Since records began in 1880, the global temperature has risen 0.85 degrees Celsius." (There is a comma missing, and "rose" should be "has risen" for correct verb tense.)

3. B - The sentence should be: "This customer has been here many times, but he has never bought anything." (The verb tense should be consistent, so "never bought" should be "has never bought".)

4. C - The sentence should be: "Regular exercise has helped her sleep better. She no longer feels tired in class now." (The verb tense should be consistent, and "doesn't" should be "no longer" for better expression.)

5. D - The sentence should be: "His health has improved over the last few years. Now he lives and works much better." (There is no grammatical error, but it's a suggestion for better expression. A more natural way to say it is: "His health has improved significantly over the last few years, and now he lives and works much better.")
