Answer:
“The Celebrated Jumping Frog of Calaveras County” is a short story written by Mark Twain. It was published in November 1865 in the New York Saturday Press. This story preceded the novels that made Twain famous, including The Adventures of Huckleberry Finn. For the public in the United States, it cast Twain as a master of humor and dialect.
In the story, a narrator from the East visits a mining camp during the gold rush in California. His friend sent him to find information about a Reverend Smiley. He encounters Simon Wheeler, who begins to tell him a story about a Jim Smiley. Wheeler tells a tall tale about Jim Smiley’s gambling.
Explanation:
The two examples which correctly punctuate an essential expression or element in the sentence are:
Architecture, so popular with Native Americans, is still a flourishing art.
Mexico, where sports are popular, has hosted the Olympic Games at the World Cup.
Some constituents that alter a sentence are indispensable and restrict the meaning of an altered word or prhase, whereas others aren't indispensable and don't affect its meaning. The first ones are separated from the main idea using commas.
Mexico City is home to several museums that display the country’s past. Here we don't have any non essential element.
The National Historical Museum, which is in Chapultepec Castle, is concerned with Mexico’s history since the Spanish conquest. Here, information can't be ommited and in fact, shouldn't be set off with comas, since such expression contains essential information (it is not any National Historic Museum but the National Historic Museum which is in Chapultepec Castle).
It adds emphasis shows how common it is for them
