Logical Reasoning - Essential Part

Exercise :: Essential Part - Type 3

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

A. love
B. church
C. ring
D. marriage

Answer: Option D

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

A. buildings
B. textbooks
C. teachers
D. meetings

Answer: Option C

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

A. desserts
B. directions
C. cookbook
D. utensils

Answer: Option B

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

A. athlete
B. actor
C. signature
D. pen

Answer: Option C

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

A. enclosure
B. prisoner
C. animal
D. zoo

Answer: Option A

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.
