High School Placement Test (HSPT) Practice Test

The thruway has more lanes than the parkway. The parkway has fewer lanes than the highway. The thruway has more lanes than the highway. If the first 2 statements are true the third is:

1. true

2. false

3. uncertain

4. none of the above

The correct answer is: uncertain

The reasoning involves understanding the relationships between the number of lanes on the thruway, parkway, and highway. The first statement establishes that the thruway has more lanes than the parkway. The second statement tells us that the parkway has fewer lanes than the highway, which implies that the highway has more lanes than the parkway. However, the relationship between the thruway and the highway is crucial for determining the truth of the third statement. While the first two statements give us a clear comparison between the thruway and the parkway and between the parkway and the highway, they do not provide a direct relationship between the thruway and the highway. Therefore, it is possible for the highway to have more lanes than the thruway, the same number of lanes, or even fewer lanes than the thruway, based on the information given. Given this ambiguity regarding the relationship between the thruway and the highway, the truth of the third statement cannot be definitively determined. Thus, labeling the third statement as uncertain is appropriate, as it reflects the lack of conclusive information connecting these two road types.
