This happens quite a lot in verbs e.g run to running. It is because you double the last consonant in a one-syllable noun for it to become a verb. (Keep in mind there are exceptions to this rule.)
The answer is:
<em>Yesterday</em><em>, Darius went to the store </em><em>because </em><em>he wanted food. </em><em>At that moment,</em><em> he ran into his teacher there </em><em>and </em><em>they talked about his latest project </em><em>for a long time</em><em>. </em><em>When he arrived home</em><em>, he decided to base his project on gourmet cooking.</em>
Transitions connect ideas between sentences and paragraphs, providing cohesion and showing how different concepts relate to one another. Temporal transitions express time, frequency and duration, as well as introduce a beginning, a middle and a closure.
The sentence that uses parallel structures is B) My three favorite activities are writing, reading, and going to the library.
A parallel structure means that the same form of a verb is used in a sentence, and as you can see, here only gerunds are used - writing, reading, going - they all have -ing in the end.
The other sentences don't have a parallel structure because they don't use the same forms.
Is this a question I’m not sure If it is :/
