The disease polio once sickened thousands of children every year.

The data best support which of these statements?
Introducing a vaccine for polio had no effect on the number of cases of polio diagnosed each year.
The polio vaccine was effective in protecting thousands of people from this disease.
The vaccine proved ineffective because cases of polio rose between 1957 and 1959.
The sources of the data are not reliable and, therefore, the data should be ignored.

Indira tested whether a tomato plant grew faster in part shade or full sun. The table below shows the height of each plant after 0, 10, 20, and 30 days. What is one conclusion Indira can draw from her data?
All plants grow taller in full sun than they do in part shade.
Tomato plants need to be placed in full sun in order to grow.
Tomato plants grown in full sun will produce more tomatoes.
The tomato plants grew taller in full sun than they did in part shade.

A research group has discovered that damselflies, a type of dragonfly, are being infected by a particular type of aquatic protozoan. Both young and adult damselflies are not directly infected by the protozoan but contract the infection from the prey they eat. The graph shows the percentage of adult damselflies infected by protozoans during the summer and early fall. Which of the following conclusions is supported by the graph?
Infection in embanked ponds increased during the sampling period.
Protozoans were more common in creek-fed ponds than embanked ponds.
Protozoans reproduce more quickly in embanked ponds than creek-fed ponds.
Infection in creek-fed ponds remained constant throughout the sampling period.
If students would like to examine the inner structure of chloroplasts, what microscope would be best suited for this task?
