Question

Kerry made a simple flashlight. She recorded
the following statements in her lab book. Which
statement is an inference?
A. The wire was 35 cm long.
B. The flashlight contained a battery.
C. The plastic switch was better than the metal
switch.
D. The bulb was lit for 20 minutes before it burned
out.

Answer 1

Answer:

The answer would be B. All the other answers can be possible if it was a more sophisticated type of flashlight. But since she made a pretty simple one, it must be something that all flashlights have in common with one another and all flashlights need a battery to function. So the right answer should be B. GOOD LUCK :)
