A metaphor is the figurative language demonstrated
A writer should use a reciprocal pronoun when:
B. two or more subjects of the sentence are also objects.
<u>Reciprocal pronouns</u> (<em>each other</em> and <em>one another</em>) are used to indicate that two or more people are carrying out a given action. A writer should use them as objects when they have already been mentioned as subjects. For example:
<em>Gary and July could not wait to give the presents to </em><em>each other</em><em>. </em>
Here's some tips about formal language:
1. Usually, it's best to replace abbreviations with their original word. For example, if you wanted to say "it's", you'd say "it is".
2. Use vocabulary words that are more descriptive. This doesn't nessesarily mean more complicated words. For example, if you were to say "Jellyfish can live without causing harm to people", instead of "live", you could say "thrive".
3. This is just a Grammar mistake - "jellyfishes" isn't a word, but "jellyfish" is (just like "fishes" isn't a word).
Hope this helps!
The second one is the best answer
