I've never heard any of these.

To determine which sentence is a commonplace assertion, we need to identify the statement that represents a widely accepted belief or a general observation. Let's break down each sentence:

A. "We all know that Texans are mad about football, and the players usually get the attention."
This sentence expresses a common belief or observation about Texans and their love for football. Therefore, this sentence is a commonplace assertion.

B. "Known as the Allen Eagles Escadrille (French for 'squadron'), Allen's band is considered the largest in the country-high school or college."
This sentence provides specific information about Allen's band being the largest in the country, but it does not represent a commonplace assertion.

C. "At some small schools, roughly half of the student body is in the band."
This sentence states a specific observation about some small schools, but it does not have the general acceptance or widespread belief needed for a commonplace assertion.

D. "Griffin's organization was formed in 1991 to better represent small schools at band competitions."
This sentence provides factual information about Griffin's organization, but it does not present a general belief or observation.

Therefore, the sentence that is a commonplace assertion is option A: "We all know that Texans are mad about football, and the players usually get the attention."
