From option 1 - The best assumption for claim that 'Pleasure is desirable' is everyone desires pleasure. So it is correct assumption.

From option 2 - The assumption some persons desire pleasure is not correct for claim that 'Pleasure is desirable'. So it is not correct assumption.

From option 3 - The assumption everyone desires something is not correct for claim that 'Pleasure is desirable'. So it is not correct assumption.

From option 4 - The assumption pleasure is essential is not correct for claim that 'Pleasure is desirable'. So it is not correct assumption.

Hence, "option 1" is correct answer.

Additional Information

1. Read statement with an approach that assumptions would be true with regard to statement.
2. Do not go too logical with statements. Analyze given information and assumption must only be made based on information in statement. Do not over-complicate it.
3. Common assumptions can always be followed but or than that do not align statement with General Knowledge or or facts
4. Use elimination method if you are unable to apprehend answer. Read statement and n assumptions given in options, you shall notice that a few of m will most definitely not follow. Eliminate m and n choosing from lesser options may prove to be more convenient
5. One thing to make a note of is that assumption is something that author believes to be true so while choosing correct option, keep this thought in mind as well. If any option contradicts statement, n that assumption will not follow.

The logic followed is:

In biological terms, a human being, or human, is any member of mammalian species Homo sapiens, a group of ground-dwelling, tailless primates that are distributed worldwide and are characterized by bipedalism and capacity for speech and language, with an erect body carriage that frees hands for manipulating objects.

The most vital organ for survival are:

Humans have five vital organs that are essential for survival. These are brain, heart, kidneys, liver, and lungs.

The human brain is body's control center, receiving and sending signals to or organs through nervous system and through secreted hormones. It is responsible for our thoughts, feelings, memory storage, and general perception of world.

The human heart is responsible for pumping blood throughout our body.

The job of kidneys is to remove waste and extra fluid from blood. The kidneys take urea out of blood and combine it with water and or substances to make urine.

The liver has many functions, including detoxifying harmful chemicals, breakdown of drugs, filtering of blood, secretion of bile, and production of blood-clotting proteins.

The lungs are responsible for removing oxygen from air we brea and transferring it to our blood where it can be sent to our cells. The lungs also remove carbon dioxide, which we exhale.

So, humans can survive without eyes, nose, hands but heart is most vital organ without it we cannot survive. 

Hence, correct answer is "Heart".

Important Points

• Our heart is made up of muscles and it is called Myogenic.
• The pericardium is outer covering of heart.
• In a human embryo formation of heart starts at age of four weeks.
• William Harvey is called far of blood circulations.
• As in human heart, blood enters twice so it is called Double circulation. 
• The left ventricle is largest chamber of heart.
• The right ventricle has thickest wall.
• The auricle is chamber of heart which receives blood.
• The ventricle is chamber of heart which sends blood.
• The right auricle receives CO₂ rich blood from body cells.
• The left auricle receives O₂ rich blood from lungs.

The main statement is: When government taxes, it also facilitates

Check all options according to main statement:

1) CD

C. Government facilitated

D. Government did not facilitate

Statement C is positive while statement D is negative. So  two statements are logically not consistent.

2) BA

3) DA

D. Government did not facilitate

A. Government taxed

Statement D is negative while statement A is positive. So  two statements are logically not consistent.

4) AC

A. Government taxed

C. Government facilitated

Statement A is positive and statement C is positive. So  two statements are logically consistent.

Hence, ‘AC’ is correct answer.

Given statement: If my mor cooks dinner, she garnishes extra cheese for me.
