## Step 1<br />The problem is a reading comprehension question in Spanish. The text talks about Rivera, who created a visual image of modern Mexican identity in the frescoes he painted from 1929 in the National Palace of Mexico. The narrative, which illustrates the history of the country from the pre-Columbian era, occupies the three walls located in front of the main staircase of the building.<br />## Step 2<br />The question asks us to identify the type of artwork Rivera created in the National Palace. The options are: an oil painting, a lithograph, a mural, or a watercolor.<br />## Step 3<br />Given the context of the text, which mentions Rivera's frescoes in the National Palace, the correct answer is "un mural". This is because frescoes are a type of mural painting, which is a large-scale painting applied directly to walls or ceilings.
