<span>Sand dunes can encroach on human habitats. Sand dunes move through a few different means, all of them assisted by wind. One way that dunes can move is through saltation, where sand particles skip along the ground like a rock thrown across a pond might skip across the water's surface. When these skipping particles land, they may knock into other particles and cause them to skip as well. With slightly stronger winds, particles collide in mid-air, causing sheet flows. In a major dust storm, dunes may move tens of meters through such sheet flows. And like snow, sand avalanches, falling down the steep slopes of the dunes that face away from the winds, also moving the dunes forward.

The correct answer is Option D) They supported the United States, hoping for independence.
The United States entered overseas war against the Spanish in the American-Spanish war which lasted from 1898 to 1902 and eventually turned into the American-Filipino war.
Before the arrival of the Americans, Philippines had been annexed and become a colony of Spain.
When the American-Spanish war started many Filipino rebels actually supported the American war effort in the hopes that the Spanish defeat would lead to their independence.
This however, did not happen as the Philippines eventually became an American colony.
