Logical Reasoning - Essential Part

Exercise : Essential Part - Type 3
Directions to Solve
A good way to approach this type of question is to use the following sentence: "A ______ could not exist without ______.". Find the word that names a necessary part of the underlined word.

1.
wedding
love
church
ring
marriage
Answer: Option
Explanation:
A wedding results in a joining, or a marriage, so choice d is the essential element. Love (choice a) usually precedes a wedding, but it is not essential. A wedding may take place anywhere, so a church (choice b) is not required. A ring (choice c) is often used in a wedding, but it is not necessary.

2.
faculty
buildings
textbooks
teachers
meetings
Answer: Option
Explanation:
A faculty consists of a group of teachers and cannot exist without them. The faculty may work in buildings (choice a), but the buildings aren't essential. They may use textbooks (choice b) and attend meetings (choice d), but these aren't essential either.

3.
recipe
desserts
directions
cookbook
utensils
Answer: Option
Explanation:
A recipe is a list of directions to make something. Recipes may be used to prepare desserts (choice a), among other things. One does not need a cookbook (choice c) to have a recipe, and utensils (choice d) may or may not be used to make a recipe.

4.
autograph
athlete
actor
signature
pen
Answer: Option
Explanation:
Without a signature, there is no autograph. Athletes and actors (choices a and b) may sign autographs, but they are not essential. An autograph can be signed with something other than a pen (choice d).

5.
cage
enclosure
prisoner
animal
zoo
Answer: Option
Explanation:
A cage is meant to keep something surrounded, so enclosure is the essential element. A prisoner (choice b) or an animal (choice c) are two things that may be kept in cages, among many other things. A zoo (choice d) is only one place that has cages.
