Shalanda (7 months) crawls over to a rattle and places it in her mouth. It shakes and makes a noise. Her eyebrows rise up and her hands start to shake. She begins to giggle. She crawls back over to the toy shelf and gets another rattle. She again puts it in her mouth and nothing happens. She begins to cry. The early childhood educator goes over and picks her up. She puts her in the high chair and tries to feed her lunch. What is the probable reason for Shalanda's different reactions to the two rattles?
1) The first rattle was broken and didn't make any noise.
2) Shalanda was tired and hungry when she tried the second rattle.
3) The second rattle was broken and didn't make any noise.
4) Shalanda was scared by the noise of the first rattle.
