Students test the amount of water retained by different types of soil. Equal amounts of soil were added to four funnels with filters, then the same volume of water was poured through each soil sample. To determine the amount of water retained by each soil sample, the student would –

• Add the amount of each soil sample to the volume of water poured in.

• Divide the total volume of water poured in by the number of samples.

• Subtract the volume of water collected from the volume poured in.

• Multiply the volume of water poured in by the number of soil samples.

Which of the following is a renewable resource?

• oil

• crops

• coal
