When i turned fifteen, my uncle bought me a model rocket. i was skeptical at first, thinking it was a toy for a kid. but my uncle explained that it contained everything needed for a real launch, from an engine to a parachute.

a. by crediting the inventor of the rocket

b. by identifying the parts of the rocket

c. by comparing the rocket to a toy

d. by explaining how to launch the rocket

the answer is "b" on

B. by identifying the parts of the rocket is the correct answer.

Explanation:

To indicate the correct answer, let's use the discarding method.

Letter A is incorrect because the name of the inventor of the rocket is not relevant to indicate the necessary parts for a real launch.

Letter C is incorrect because it could go in the wrong direction, meaning that the boy could me more skeptical if the rocket were compared to a toy, even though some parts were similar.

Letter D is an important part to let the boy know how the rocket was launched, but this could be also shown with a toy or any other item, as long as it has a similar shape.

Finally, letter B is correct because a model is a representation (3D) of someone or something, and it usually shows in detail (as much as possible) the parts of a machine, like in the question. By this, the boy would understand why the model is not a toy.

there on the beach was a struggling turtle.   around its bright green neck was a loop of soda can rings.   in order to the planet, i have made a few changes to my life.   the first change is reducing the number of straws used. the second change was to recycle.   finally, i have worked hard to clean up litter.   it is important to clean our ocean.

you may not think straws have a large impact but they do.   imagine for every straw you sip out of a poor, , adorable turtle is being harmed.   one way i chipped in to is by using metal straws.   these straws are reusable and inexpensive.   another change is simply turning down straws.   by refusing a straw, i’m the turtles one drink at a time.  

however, the ocean just doesn't have turtles.   there are lots of creatures that live there and are harmed by all the litter.   to prevent litter from growing it’s important to recycle.   for me, i have started to buy most goods that are made out of recycled material.   pura vidas, chacos, purses, and too many other items to even count.   plus, when you buy those products they give money to charities.   not only am i the environment, but i’m also feeling better about my self.   finally, i have worked hard to clean up litter.   it is important to clean our ocean.
