A group of 35 homes in a small town used only fossil fuels to warm their homes during adverse weather. A researcher collects data on the average monthly temperature in the town for a year. The table shows the data. Based on the data, what is a likely conclusion of the researcher?

• December had a lower consumption of fossil fuels than November.

• January had a greater consumption of fossil fuel than December.

• In the months of November and February, there was no consumption of fossil fuels.

• In the months of April and November, the consumption of fossil fuels was about the same.

A student conducted a study to see if environmental precipitation amounts effect the amount of carbohydrates in a cactus. Which statement is a correct conclusion to the experiment?

• The amount of precipitation in an area and the amount of carbohydrates in a cacti follow an increasing growth curve.

• Areas with small amounts of precipitation will produce cacti with large amounts of carbohydrates.

• Cacti with small amounts of carbohydrates are found in regions with small amounts of precipitation.

• Precipitation amounts in a given environment have no effect on the amount of carbohydrates in cacti.

A scientist performed an experiment to identify the effects of soil salinity on plant growth. He took two basil plants and planted them in similar pots. He watered Pot 1 with normal water and Pot 2 with saline water, and measured the heights of the plants every week for 10 weeks. The graph shows the data recorded. Which statement uses evidence from the graph to conclude that plant growth is adversely affected by soil salinity?

• The height of the plant in Pot 2 was more than the plant in Pot 1 at the end of the experiment.

• The heights of both plants were almost equal for the first six weeks.

• The height of the plant in Pot 1 was more than the plant in Pot 2 at the end of the experiment.

• The heights of both plants increased during the experiment.
