Read the passage below and in the text box answer the question that follows. Part 3 America Doesn’t Need an Official LanguageBy Carlos LozadaOpinion Columnist (New York Times, March 6, 2025) So, it’s not that I reject the arguments about efficiency and empowerment; I just question the need for a presidential order to enshrine them. I was tested on my English skills when I became a U.S. citizen a decade ago, but the market tells immigrants we must learn the language, more clearly than the government ever could. Where Trump’s order moves from redundancy to confusion to cynicism is in its statement that a single official language will “cultivate a shared American culture” and “reinforce shared national values.” After all, what is our shared culture if not the mix of cultures — including languages — that make and remake America every day? You may as well argue that a single cuisine or a single style of music or a single literary genre is more truly American than any other. Thank God that my immigrant childhood means I can read Cervantes and Mario Vargas Llosa in Spanish and Shakespeare and Toni Morrison in English. If I can, why wouldn’t I? I grew up with two languages, and I regret not learning a third the way other people learn a second. Think how much richer the nation would be if we all knew more languages, not fewer, if we embraced a multiplicity of influences rather than shielding ourselves from them.

Read the passage below and in the text box answer the question that follows. Part 2 America Doesn’t Need an Official LanguageBy Carlos LozadaOpinion Columnist (New York Times, March 6, 2025) In his March 1 executive order designating English as the official language of the United States, President Trump asserts that a single shared language is “at the core of a unified, cohesive society,” that it serves to “streamline communication,” promote efficiency and “empower new citizens to achieve the American Dream.” On these points, I have little disagreement. Just about every immigrant I’ve ever known in the United States — starting with my father — has sought to learn English for just those reasons. It was relatively easy for my sisters and me to pick it up as kids, and my mother had learned it well from the beloved American nuns who taught her in Peru. But my dad, coming to it later in life, always had to work at it. And work he did. His errors of pronunciation never kept him from speaking English, even singing it, loudly and proudly. I cringed a bit at the time. Now I cringe at the memory of my cringing. Had English suddenly become the official language of the United States via an executive order from President Gerald Ford, I can’t imagine that my father would have learned it any faster or that he would have felt more encouragement to do so. The need to work, to provide, was all the incentive he required. In the textbox, use your own words (not not copy from the text) write 1-2 complete sentences to answer the question. Question: What is President Trump’s main reason to make English the official language of the United States, and what does the author think about it?
