Even though it is possible to answer this question without the passage to which it refers, I will add it here to make answering easier:
Then I heard about a summer job through my uncle who was a dentist. He introduced me to one of his patients who had a business selling audio-visual equipment for big light and music shows. He was looking for some new, better equipment. I spent all summer when I was sixteen building high-powered light-controlled systems that synchronized many Kodak projectors at once, as many as sixty-four to 120 of them, and reduced the cumbersome machines from the size of a refrigerator to the size of a toaster. Not only was this invention used in theaters, but it was sold to the Museum of Natural History and the New York Planetarium to project views of the heavens on the ceiling. To make this new device I had bought every kind of electrical equipment I could find, and still had money left over.
Answer:
The detail that shows that Kamen's light-controlled systems were very good is:
C. One of his inventions was used in theaters, the Museum of Natural History, and the New York Planetarium.
Explanation:
If Kamen's systems were not good, they wouldn't have been used at all, no matter how much time and money he had spent developing them.
<u>The proof that they were good can be found in the line where it is said, "Not only was this invention used in theaters, but it was sold to the Museum of Natural History and the New York Planetarium to project views of the heavens on the ceiling." To be used in places such as the Museum of Natural History and the New York Planetarium, the systems must have had excellent quality. At those places, exhibitions are taken seriously, and they would have invested in good equipment and systems to make sure the quality was the best they could get.</u>
I think the correct answer would be A. The infinitive is the most versatile verb form because it can be used as a verb, noun, adjective and even an adverb. An infinitive verb is classified as a non-finite verb wherein it could be used as the principal verb in a sentence. The infinitive verb form of a verb is commonly preceded by the word "to". For instance: to run, to dance, to swim, to sleep etc. An example of an infinitive verb as a noun is: To swim a mile is her greatest dream. The infinitive form of the verb is "to swim"
Answer:
when you came to different country and you talk another lenguage.
Explanation:
Passive voice is used in a clause whose subject is unknown , unimportant , common , or obvious. In passive voice object will replace the subject and subject will be removed.
Active voice is used in a clause or a sentence whose subject expresses the main verb's agent. The subject and the object of the sentence come in it's order in active voice .
Example : People speak spanish in spain => active voice , people is the subject.
Spanish is spoken in spain => passive voice , ( the subject is obvious to us )
The pic above :
number 1 : As you see in that sentence the subject of the sentence (we) has came directly in the sentence so this is an action voice .
number 2 : But in this one when you read the sentence , you immediately ask yourself "who ?" so the subject is unknown therefore this is an passive voice .
I hope it helped.
