Images constitute integral parts of technical documents. An effective way to display images within a technical document is to distribute the images around the page and document. A document that portrays information accompanied by images and diagrams is much easier to be understood than one with only pure text descriptions. It is important to state that images are useful resources that allow the reader make sense of the information provided in a text, since images help the reader clarify if they are used carefully and with suitable captions.
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).
