Many individuals become wiser as they age, but their performance on tasks that require speed in processing information starts to decline. This illustrates how throughout life some dimensions or components of a dimension expand and others shrink, or how development is:

Multi-directional

Explanation:

  The multi-directional development is one of the concept that helps in explain about the changes occurring in the uni-direction with some predicted growth, gain and also the unpredictable transformations.

 In this type of development the human behavior are organized based on their performance which is required in processing the given data or information.

According to the given scenario, the performance of the people may vary based on their individual speed and the given situation is best illustrating about the dimension of multi-directional development process.

 Therefore, Multi-directional is the correct answer.      

the median of the data is 4.

step-by-step explanation:

the median means the middle number of a given number.

to decide which one is the median, arrange in ascending or descending order. but sometimes, you may find two(2) number in the middle, but it's easy, just add them together and divide by 2.

so,   determine the median of the data. 2, 3, 3, 4, 5, 7, 9

it is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9

our answer is 4.

hope this !

answer; (d) none of the above;
