Which detail from paragraph 2 or 3 best shapes the idea that requiring Americans to learn English is unnecessary?

(2) According to the U.S. Census Bureau, 97 percent of Americans currently speak English "well" or "very well." Even among those immigrants who come to this country speaking other languages, most passionately desire to be proficient in English--for their own economic survival and to secure economic opportunity for their children. Today's immigrants are learning English faster than previous generations of immigrants; English classes are in such high demand that some stay open 24 hours a day...
(3) So maybe the reason for this bill is to save printing costs. A recent GAO report found that a mere six one-hundredths of one percent of federal documents produced since 1990 are in languages other than English; this works out to be only 256 out of 400,000 federal documents. I would also point out that most of those non-English documents were created to serve the Spanish-speaking residents of Puerto Rico. So I guess it is not the cost of publishing in other languages that justifies this limitation.

Well, 2 shows details of immigrating people and how they learn to speak English faster than before, and also adds details to how English classes are open 24 hours a day because they are in such high demand.

But 3 shows that the federal documents are being produced in multiple other languages than English, leaving others to not necessarily have the urge to speak English.
