Five-year-old avery watches as someone pours liquid from a short, wide container into a taller, narrower container. she believes that there is more water in the taller container, indicating that she is in the stage of cognitive development.

Avery is in the preoperational stage of cognitive development.

Explanation:

According to Piaget's Cognitive Development Theory, Avery is still in the preoperational stage, which goes from 2-7 years of age.

This stage, as the name states, occurs before the child can formally carry on operations. During this time the child still thinks in a very concrete way, not being able to do this in a more abstract way and he/she struggles with logical thinking.

During this stage the child also struggles with constancy, which is the understanding that an object is still the same even if it changed its composition or was moved.

This can be explained through Avery's failure to understand that the water is the same, that there is no more and it was simply moved to a taller container which only gives the illusion that there is more of it.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
