“You can look it up”
	When looking for information, a single item might be the answer, but a table is more likely • “Who is taking FIT100”? Table of students • “Whose mile run time £ 4:00?” Runner table • “Who won 2003 Grammy for ‘Best New Artist?” A table containing only a single row • “Who is president of UW?” Empty Table
