Read the passage. In 1856, the government was taking steps to create a public-school system. Progressing, the legislature passed the first public-school law in 1860. This encouraged other districts that were building schools in other parts of the territory. The University of New Mexico was built for the increasing population of Albuquerque in 1889. Established schools became more numerous in some areas by the early 1900s.
Which underlined word is a past participle?

Progressing
building
passed
Established

pretty sure its passed :)

for me, i'd go with (c) satisfied or (b) overjoyed because if you read it a couple of times, it makes since that it is c or b. it can't b (a) angry because booker was never angry about anything. at the end of the paragraph, booker states, "i think there are not many men in our country who have had the privilege of naming themselves in the way that i " i think that sentence kind of gives away the also, some words in the paragraph can also you like for example, "indulged," "calmly," "perplexity," "privilege," and defining words that you don't know, can you understand more of that paragraph and it can also increase your comprehension. : )

i'm really rally sorry if i'm incorrect, but if i'm hope this ! : )
