A company claims in their promotional materials that their apples taste better than all other apples. Which of the following best describes this claim?

• The accuracy of the claim can't be evaluated because you can't taste all apples

• The accuracy of the claim can't be evaluated because "better" is an opinion.

A group of engineers have developed four different models of a car. They have recorded data about each model’s miles driven per gallon. What would be the best way for the engineers to communicate the results of their testing?

• detailed drawings of each of the cars

• a bar graph comparing miles per gallon

• a measurement of the size of the gas tank in each car

• a data table showing the number of miles each car traveled during testing

Scientists or engineers often build a prototype of a design that they can test. Observing how the prototype performs shows the engineers how their design works. Which is another tool scientists use that is similar to a prototype?

• a balance

• a bar or circle graph

• a model of the design

• an experiment using the design
