An ACT Science question asks you to combine information from a table and a figure. The most efficient strategy is to:
Answer: Locate the specific data each source provides and cross-reference them
Targeted cross-referencing of the relevant data points is faster than full reading.
A graph of velocity versus time shows a horizontal line. This means the object has:
Answer: Constant velocity (zero acceleration)
A flat velocity-time line means velocity isn't changing, so acceleration is zero.
In an ecosystem study, removing the top predator causes the prey population to spike. This best illustrates:
Answer: A trophic cascade
Effects rippling through a food web after removing a predator are a trophic cascade.
A titration graph shows pH rising sharply at the equivalence point. This sharp rise indicates:
Answer: The acid has been neutralized by the base
The steep pH jump at the equivalence point marks neutralization.
When two variables both increase but a third hidden factor causes both, scientists warn that:
Answer: Correlation does not prove causation
A shared cause means correlation alone cannot establish a causal link.
A spectrometer reading shows an element absorbs light strongly at a specific wavelength. This absorption pattern is most useful for:
Answer: Identifying the element present
Each element has a characteristic absorption spectrum used to identify it.
A study reports results from only 5 subjects. A valid criticism on the ACT would be that:
Answer: The small sample size limits how broadly conclusions apply
Small sample sizes reduce the reliability and generalizability of conclusions.
