The objects on Maria’s shelves are disorganized and often fall to the floor. She thinks of four ways to solve this problem and numbers her designs 1, 2, 3, and 4. For each design, she builds a prototype and tests it. She records data on how well each design meets her criteria.

Which design best meets Maria’s criteria?

• design 1

• design 2

• design 3

• design 4

An engineer designed four braces to offer comfort and support for people who have had knee surgery. The table shows the results from a survey of 100 people who tried the four prototype braces.

Which conclusion can be made from the information in the table?

• Brace A is preferred by a majority of the people surveyed.

• Brace C would be the best choice for comfort and support.

• Brace B would most likely keep people from becoming injured again.

• Brace D is the brace that can most likely be improved by further design.
