Teacher: What are the _?_ physical needs of human life?
Student: Air, Food, water, shelter, warmth, rest.
Choose the best option:
needed
non-essential
essential
essentials
Answer And Explanation
The answer is ‘essential‘ because:
essential ⓪ (the correct answer）
essentials is plural; we need a singular answer.
needed is redundant (repetitive; the verb ‘need’ is used later in the sentence).
non-essential means ‘non-essential’ means not essential (not necessary).
