Details/Examples to Explain, Infer (Text) Practice Test

Read the passage. Every fall, millions of monarch butterflies migrate from Canada and the United States to central Mexico. Some travel up to 3,000 miles, and the trip happens as temperatures begin to drop. In Mexico, monarchs cluster together on oyamel fir trees in mountain forests. No single butterfly completes the entire round trip; it takes 3 or 4 generations to finish the full cycle. Scientists have learned that monarchs use the sun as a compass to help them navigate. Based on the passage, what can you infer about the monarch migration?

Read the passage. Archaeologists are scientists who study human history by excavating artifacts. When they find a site, they dig carefully through layers of soil and record where each item is found. They use tools like trowels, brushes, and screens so fragile objects do not break. Every artifact is photographed, measured, and cataloged before it is removed. Archaeologists can also use scientific dating methods to estimate an artifact’s age. Based on the passage, what can you infer about why archaeologists work slowly?
