Answer:
1. The time difference between the arrival of the first P-Wave and S-Wave would be less than 4 minutes.
Explanation:
S waves are slower than P waves, even if emitted at the same time. In this case, we can say that if a station is located close to the earthquake epicenter, the station would receive these waves quickly. The P wave would be received first, since it has a higher speed, the S wave would arrive soon. As you did not provide the times when each wave was emitted, we cannot accurately state the time when each wave would be perceived by the station. However, as the station is close to the earthquake, we can say that the time difference between P and S waves would be seconds, that is, less than 4 minutes.

Answer: b. Neutral stimulus
Ivan Pavlov is known for his studies about classical conditioning where one can learn through establishing associations between different events and stimuli.
In his experiment about dogs, the bell represents neutral stimulus that is paired with food as unconditioned stimulus, which produce involuntary bodily response such as salivating.
Therefore, the bell as neutral stimulus before the experiment began can now trigger a response all on its own to that produced by the food. This means that an individual has learned that neutral stimulus is equals to something good just like the unconditioned stimulus.
