Solar power

29 Emergency call boxes, often found along the side of the road in remote locations, are frequently solar-powered. They usually have lights on them, which provide illumination every night.

30 Like wind turbines, they’re hard to service, so they’re built to last for a long time. As long as they’re kept free of dust and debris, solar panels will generally last as long as the electronics connected to them.

31 A solar panel’s wires and circuits will eventually succumb to corrosion, but solar panels in a dry place, with well-built electronics, could easily continue providing power for a century if they’re kept free of dust by occasional breezes or rain on the exposed panels.

32 If we follow a strict definition of lighting, solar-powered lights in remote locations could conceivably be the last surviving human light source.

33 But there’s another contender, and it’s a weird one.

The author’s purpose in opening this section by introducing the topic of emergency call boxes is probably to:

Answer choices for the above question

A. Explain the process by which solar panels work.

B. Inform readers that lighted call boxes are often located in areas where there are few humans.

C. Describe why solar panels can last for so long without human intervention.

D. Tell readers how long a light powered by a solar panel would probably last.

Read the excerpt from the war of the worlds, in which the crowd begins to disperse just before the first martian exits the cylinder. when i returned to the common the sun was setting. scattered groups were hurrying from the direction of woking, and one or two persons were returning. the crowd about the pit had increased, and stood out black against the lemon yellow of the sky—a couple of hundred people, perhaps. there were raised voices, and some sort of struggle appeared to be going on about the pit. strange imaginings passed through my mind. as i drew nearer i heard stent's voice: "keep back! keep back! "a boy came running towards me."it's a-movin'," he said to me as he passed; 'a-screwin' and a-screwin' out. i don't like it. i'm a-goin' 'ome, i am."what options accurately depict the impact of the boy's words on pacing within the excerpt? (select all that apply.)the war of the worldsthe setting is in england, so the boy's words provide the reader with the dialect of the area. even though that slows down the plot, the boy's words contain important information. the plot's forward movement is slow at the beginning of the excerpt because there is little action. the boy's words increase the tension and counteract that lag. the narrator is not close enough to see clearly into the pit, so the boy's words provide the narrator with the information he needs, which moves the plot forward. the boy's words serve to speed up the pacing of the plot because, as he is talking to the narrator, he is running past him to get away. the narrator is not close enough to see clearly into the pit, so the boy's words provide the narrator with the information he needs, which moves the plot forward. wrong? the boy's words serve to speed up the pacing of the plot because, as he is talking to the narrator, he is running past him to get away.
