According to the opponent-process theory, if you stare at a red star for awhile (e. g., 60 seconds) and then look at a plain sheet of white paper you will see an afterimage of the star in which hue?
a. yellow
b. blue
c. green
d. red
e. purple

You will see an afterimage of the star in C. green hue.

Explanation:

The Opponent-Process Theory explains that an individual's perception of colors operates under 3 opposing systems:

An individual perceives a hue based on 2 colors but he/she can only see one of these opposing colors at once.

In this case, if you stare at a red star, you are looking at the red vs. green system so once you are done looking at the red, you will see the green afterimage of it, since green opposes red.

dear friend:

  i hope this letter finds you in soaring spirits and vibrant health. as you had expressed the wish to know about culture, traditions, and unity of india in your previous letter, in the following lines i have tried my best to give you glimpses of our culture, traditions, and unity. you will be amazed to know that our culture is the oldest culture in the world and the birth place of hinduism, buddhism, jainism, and sikhism. you won’t find any other culture as varied and multi-colored, multi-lingual as ours. each region has its own unique culture, traditions, language. there are 22 official languages in india.

  basically, india is a spiritual country with orthodox traditions. for example the people of india believe in traditions set by their wise forefathers. arranged marriages, joint-family system, universal brotherhood, vegetarianism, celebrating festivals such as diwali, holi, eid, etc., are the salient features of our culture and traditions.

  another unique aspect about our country is ‘unity in diversity’. in spite of the multi-lingual, multi-religious, multi-traditional, multi-cultural society, people live peacefully together, respecting one another’s views, cultures, traditions, and differences. i am sure you would love to visit india soon, and have a first-hand experience of the multi-colored culture. give regards to uncle and aunt. do visit india with your family and experience our hospitality.

your friend,

the united states has a federal government. the president is the head of the federal government of the united states. however, each state forms its government for administration purposes. the powers of the state governments are exercised within restricted state boundaries. and citizens participate in this government by voting.
