Option B. The Cold War practice that had a direct impact on the daily lives of many American citizens including children was called Duck and cover drills.

Explanation:

After the Soviet Union exploded its first atomic bomb, the American public became notoriously more nervous. By the early 1950, a new federal agency called Federal Civil Defense Administration (FCDA) started to educate the public on safe procedures to take in case of an atomic attack. Schools across the country were training students to dive under their desks and cover their heads. This movement became known as the "duck and cover drills" and, naturally, channeled a growing panic over the population, that was now affected in their every day lives due to the Cold War.

“the iliad” (gr: “iliás”) is an epic poem by the ancient greek poet homer, which recounts some of the significant events of the final weeks of the trojan war and the greek siege of the city of troy (which was also known as ilion, ilios or ilium in ancient times).

the  seven  days  battles  were  a series of seven battles over seven  days from june 25 to july 1, 1862, near richmond, virginia,  during  the american civil war. the  seven  days ended with mcclellan's army in relative safety next to the james river, having suffered almost 16,000 casualtiesduring  the retreat.
