Select the option that is related to the third word in the same way as the second word is related to the first word.
(The words must be considered as meaningful English words and must not be related to each other based on the number of letters/number of consonants/ vowels in the word.)
Summon : Call :: Disperse : ?

The correct option is Spread.

To solve this analogy, let us analyze the relationship between the first pair of words:
Summon : Call
The word "summon" means to authoritatively or urgently call on someone to be present. Therefore, the relationship between "Summon" and "Call" is that they are synonyms (words with similar meanings).

Now, we must apply this same synonym relationship to the second pair:
Disperse : ?
The word "disperse" means to distribute, scatter, or go in different directions over a wide area. Among the given options, the word that is a synonym of "disperse" is Spread.

Let us review why the other options are incorrect:
- Surround means to encircle or enclose, which is not synonymous with dispersing.
- Remove means to take something away or eliminate it.
- Disappear means to vanish or cease to be visible, which is a potential consequence of dispersing but not a direct synonym.

Hence, "Disperse" is related to "Spread" in the same way "Summon" is related to "Call".
