Read the following two details from the article.
1. the company's products — like virtually every bulletproof backpack on the market are
advertised as meeting "ballistic level iiia" standards, which means they can withstand
bullets from handguns and revolvers.
2. furthermore, the products - which often are tested independently by the companies selling
them - are not vetted by the national institute of justice, an arm of the justice department
that certifies body armor for law enforcement officers.
which option best explains how these details develop a central idea of the article?
(a) the details explain why the companies that sell bulletproof backpacks often test their products
independently.
(b) the details describe two methods used to determine whether bulletproof products are effective in
protecting children.
(c) the details indicate that only bulletproof backpacks that have met certain standards can be advertised
as effective
(d) the details support the idea that there is no proof that bulletproof backpacks are effective in making
children safer.

Kwan gazed out at her brother and heard his shrieks of delight as he tried to direct their marvelous flying creation. she watched it wheel, spin, and dive—a wild, colorful bird putting on an aerial display. its gold and red crepe-paper wings fluttered in the air, mimicking the flight of a predatory bird surveying the landscape for prey. it swooped and dived, perhaps discovering a possible meal, and then went airborne again to avoid the rocky terrain below. min was the falconer, guiding his bird on its path through the sky, not yet ready to call it back to the ground. but kwan grew concerned when she looked out at the dark, threatening clouds beginning to roll in off the water. when she saw the streaks of lightning within the cloud formation, she pointed to the distant storm and called out to her little brother to bring in the kite. min nodded and rolled in the kite string, bringing his bird home. “let’s go,” kwan told her brother and put her arm around him to fold him safely under her wing as they both held onto the kite. “it’s time to go home.” how does the extended metaphor in paragraph 3 affect the mood of this passage? a-it creates a feeling of silliness that captures the absurd humor of the situation. b- it creates a sense of tranquility to match the feelings of min at this point. c-it creates a feeling of fear over what may happen if the kite crashes. d-it creates a sense of awe and wonder at min's mastery of the kite.
