Example Question #331 : Comma Errors

Choose the correct form of the following sentence: 

Luke and Tony went to the gymnasium to pick up there shoes jerseys, and equipment before football practice. 

Possible Answers:

Luke and Tony went to the gymnasium to pick up their shoes, jerseys and equipment before football practice. 

Sentence is correct as it is. 

Luke and Tony went to the gymnasium to pick up there shoes, jerseys and equipment before football practice. 

Luke and Tony went to the gymnasium to pick up they're shoes, jerseys and equipment before football practice. 

Luke and Tony went to the gymnasium to pick up their shoes jerseys, and equiptment, before football practice. 

Correct answer:

Luke and Tony went to the gymnasium to pick up their shoes, jerseys and equipment before football practice. 

Explanation:

There are two errors in the sentence: (1) "There" refers to a place. Because it is being used to show possesion, it should be changed to "their." (2) A comma must be added between shoes and jerseys and removed before and to demonstrate correct usage of a comma. 

Example Question #451 : Punctuation Errors

During the final months of 2007, the prices of basic grains nearly doubled in Northern Africa, Latin America, and much of Asia, the high prices caused a global food crisis. The catastrophe sparked and incited an international debate regarding the licensing of new technologies to developing nations. One economist warned that because of the risk of unforeseen price shocks, officials should proceed very cautiously. The construction of private farms pose a serious financial threat to farmers in the United States; nevertheless, of the five most industrialized nations, the United States exports more crops.  

How do some countries cope with food crises better than others. It is technology that accounts for the majority of the difference. The rate at which countries adopt innovations depends significantly on environmental factors. These environmental factors include climate, soil and elevation. The variability in environment inhibits new technologies from gaining worldwide popularity that are suited for one particular region over another. For example, the pesticides used in Europe are much more acidic than North America. Without the different levels of acidity, pests would prevent the crops to grow.

Choose the answer that best corrects the bolded portion of the passage. If the bolded portion is correct as written, choose "NO CHANGE."

Possible Answers:

 soil, and last but not least, elevation 

soil, and, of course, elevation

soil, and elevation

NO CHANGE

Correct answer:

soil, and elevation

Explanation:

Lists with three or more items must be separated by commas. The original text contains an error because the list is missing a comma between items. The sentence should read: "climate, soil, and elevation." The answer choice "soil, and elevation" is correct.

The waitress was appeased (5). She had never seen anyone order so much food in one sitting it (6) made her slightly ill to watch him eat it all. What made it worse he had no table manner at all since (7) philosophers tend to be thinking about life and death and (8) not about using a napkin. Finally (9) as he sipped the last of his burgundy (10) Descartes made a motion for the check. The waitress asked (11) "Would you care for any desert, monsieur?" At that point, Descartes replied, "I think not" (12) and promptly vanished.
