Answer:
B. There were not enough firefighters to do all the necessary tasks.
Explanation:
We can tell from the first sentence that there was not enough help. Even without knowing any background on the story, we know there was just a thin circle of engines around the fire. In order to deprive the fuel of fire, the firefighters asked spectators to help by chopping up fences and sidewalks. This way the fire fighters could focus on the engines. 
 
        
                    
             
        
        
        
<span>To wrestle with a dilemma means to have difficulty deciding between competing resolutions of a problem.

Answer:
The best option is letter A) felt their efforts were not successful.
Explanation:
The excerpt we are analyzing here was taken from a memoir called "A Rumor of War" by Philip Caputo. Caputo recalls his experience at the Vietnam War and how he believes America's involvement in it was all for nothing.
As we can tell from the excerpt, soldiers did not seem well prepared at first. They misjudged their enemy, thinking of them as mere "peasant guerrillas". The enemies turned out to be lethal, and more and more American soldiers died each week. That "broke [their] confidence", which means they felt their efforts were not successful. In the book, the author even says he wishes he had different war stories to tell instead of the ones he actually lived. Battles in Vietnam were exhausting and never-ending; the enemy was seemingly undefeatable, hiding in jungles filled with traps and snipers.
