On a yes/no because item, decide yes or no from the data first. Then check whether the because clause is actually true. Both halves have to be right. Trend reading is in interpreting trends.
Split the choice
The choices come in pairs: two yes answers with different reasons, two no answers with different reasons. If the table shows the value went up, every “no, it decreased” choice is gone before you read the because. Then keep only the because that matches the figure, not the one that sounds like a textbook.
Looking at the wrong figure is the usual way to pick the wrong yes or no. That trap is in the right figure and the right interval.
When two viewpoints are the source
Some because clauses quote a student or a hypothesis. The clause can sound scientific and still contradict that viewpoint. Conflicting passages are in conflicting viewpoints. Passage shapes are in Science passage types.
The bottom line
Yes or no from the data. Because from the same data. A true claim with a false reason is still wrong.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
