Please help. This is an excerpt from a letter written by a soldier fighting in World War I and
sent to his mother:
The trenches stretch for miles, but even though they are
almost 12 feet deep, we can't walk around much. The
bullets and grenades rain down upon us at even the
slightest hint of movement, so all we can do is lean in
stillness, waiting, trying not to make a sound.
Which statement best represents the main idea of this source?
O A. Fighting in a World War I trench was boring and dangerous.
B. Trenches were used extensively in World War I.
C. Trenches are often dug almost 12 feet deep.
O D. The soldier's mother is worried about her son.

On a map showing the employment density of an urban area that follows the urban realms model, which of following statements best describes what the distribution of jobs might look like? (3 points) jobs closely follow major transit routes. jobs appear to be shifting from the inner to outer core. most jobs are concentrated around the central business district. jobs are distributed roughly in circles. several edge cities contain high numbers of jobs. which of these is not a criticism of the concentric zone model? (3 points) it does not accurately describe cities after the rise of suburban development. it only applies to cities that grew after the development of the automobile. it fails to address the development of cities outside of the united states. it assumes that inner-city areas will always be repurposed instead of abandoned. it places too much importance on the traditional central business district.
