The phrase "Mariana eats salad for lunch yesterday" is incorrect. That's because the word "yesterday" shows that the action that Mariana is doing happened in the past, so the words used to compose the sentence must accompany this time, to stay grammatically correct and become a sentence with coherence and cohesion.
The mistake in this sentence is the verb "eats". This verb is in the present tense and does not accompany the adverb of "yesterday" tense that is in the past tense. To fix this, we must put the verb in your past time "ate", with that the phrase should be "Mariana ate salad for lunch yesterday".
Activism is action on behalf of a cause, action that goes beyond what is conventional or routine. An example of Activism is polite request to objectional interference. Good luck!
