Question

True or False

1)
The user's first hypothesis was that the lamp wire was unplugged. The user tested that hypothesis by viewing the wire firmly plugged into the outlet.
2)
The user's first hypothesis was invalidated, so the user created a second hypothesis that the bulb was broken. The user tested that hypothesis by shaking the bulb and listening for rattling.
3)
The user's first two hypotheses were invalidated, so the user created a third hypothesis that the outlet was dead. The user tested that hypothesis by plugging a known-working lamp into the outlet.

Answer 1

Let's evaluate each statement:

1) True - The user's first hypothesis was that the lamp wire was unplugged, and they tested that hypothesis by confirming that the wire was firmly plugged into the outlet.

2) True - The user's second hypothesis was that the bulb was broken, and they tested that hypothesis by shaking the bulb and listening for rattling, which is a common method to check for a broken filament in incandescent bulbs.

3) True - The user's third hypothesis was that the outlet was dead, and they tested that hypothesis by plugging a known-working lamp into the outlet, which is a valid method to check if the outlet is functioning properly.

Overall, all three statements are true.
