Final Answer:
The correct answer is 2) More time, increased likelihood of error.
Step-by-step explanation:
When reading a graph, the number of mental operations required has a direct impact on the efficiency and accuracy of the process. Generally, the more mental operations involved, the more time it takes to interpret the graph. Each mental operation, such as calculating slopes, finding intersections, or determining trends, adds to the complexity of the analysis.
Consider a scenario where a graph requires extensive mental calculations or intricate data comparisons. In such cases, spending more time on each mental operation is likely, and as the complexity increases, the likelihood of making errors also rises. This is because the probability of making mistakes tends to grow with the number and intricacy of mental operations performed during graph interpretation.
Conversely, when fewer mental operations are needed, the interpretation process tends to be more efficient, requiring less time, and there is a decreased likelihood of errors. Therefore, option 2) "More time, increased likelihood of error" accurately captures the relationship between the number of mental operations and the efficiency and accuracy of reading a graph.
