What is the relationship between the pairs in the following analogy? castle : moat as head : helmet

A. one covers the other
B. one purchases the other
C. one protects the other
D. both are used in urban environments

The relationship between the pairs as used in the analogy given is protection.

Castle : moat

Head : Helmet

Both the moat and helmet provides a form of tentative defence for a castle and the head respectively.

• The moat may be described as a defensive structure usually in the form of a water body such as ditch, dam or lake build around a castle to provide tentative security to the castle.

• An helmet a form of head gear worn in other to provide safety to the skull in case if accident.

The moat surrounds the castle rather than covers it, Hence, the most appropriate option is ;  . both pairs are related in terms is that one protects the other.

C. One protects other.

Explanation:

First, you should eliminate what isn't reasonable.

D says "both are used in urban environments" this answer choice doesn't seem that reliable, and it doesn't relate AT ALL to the analogy, because castles and helmets aren't even of modern time, and more medieval times.

B. says "one purchases the other" this doesn't make any sense, because a castle doesn't buy a moat, and a head doesn't buy a helmet, though you can buy them, they don't buy each other.

Now you are left with A and C

A says covers the other, while C says protects the other. If you do not know, a moat of a castle is actually the bridge in front of a castle that can be considered the passage of entry and the exit as well. This can be considered as a form of protection to keep out any enemies. So, the actual answer is C.

where are the following words.. you cant just ask a question and expect people to know the choices.
