The student wants to present a difference in the type of armor used by early and later knights. Which choice most effectively uses relevant information from the notes to achieve this goal?

While researching a topic, a student has taken the following notes:

• - Chain mail armor was invented before the Middle Ages.

• - It covered only the chest, so early medieval knights also wore a helmet and carried a shield.

• - At the end of the 13th century, near the end of the Middle Ages, the first plate armor was created

• - Knights quickly began using it to cover their entire bodies.

• - In highly stratified medieval society, armor served as a status symbol.

• Both chain mail armor, which was used in the early Middle Ages, and plate armor, which was used later, covered the wearer's chest.

• The armor used by knights in the late Middle Ages consisted of solid plates, which covered the wearer's full body.

• Whereas early medieval knights wore armor that left them partially exposed, knights in the late 13th century used plate armor, which offered full protection.

• In the late thirteenth century, knights began to wear plate armor that covered the wearer from head to toe.

The student wants to emphasize the mystery surrounding the sculptures. Which choice most effectively uses relevant information from the notes to achieve this goal?

While researching a topic, a student has taken the following notes:

• - The "colossal heads" are the most famous artworks produced by the Olmecs, the first Mesoamerican civilization (1200 BCE – 400 CE).

• - Scholars theorize that the heads depicted Olmec rulers.

• - They were carved from boulders weighing between 6 and almost 50 tons.

• - The monument at Takalik Abaj in Guatemala is the only sculpture outside the Olmec heartland.

• The faces, which scholars believe may represent Olmec rulers, sit below headdresses of unknown significance.

• Only one of the heads is located outside the Olmec heartland.

• While all of the heads are immense, they do vary in size: the smallest weigh six tons, whereas the largest ones weigh 50.

• The Olmecs, who created the first civilization in Mesoamerica, carved a series of enormous stone heads.
