Answer:
A passive sentence is a sentence that happened in the past.
Example: I ate my ice cream. I is my subject and ate is my verb, and ate is a passive word.
Example 2: I am eating my ice cream . I is the subject again but the verb is different. Instead, this sentence is telling you that i am eating ice cream right now, so that means that this is a present verb.
Examples of passive verbs: ate, ran, jumped, coughed, and walked
Answer:
she cooked for three hours when the guests arrived
Answer:
Air
Explanation:
A siren is a device that produces sound waves due to the flow of air through a series of holes. It consists of a rotating disk which has series of holes drilled at required distances to one another, and a nozzle through which air flows.
The nozzle is arranged in such a way that it forces air through the holes of the rotating disk, thus producing sound with appropriate frequency.
Sirens are used for security purpose, in ambulances etc.
The correct answer is C. Central Ideas are only found in literary works
Explanation:
Central ideas are the main point, though or idea a writer wants to explain to the audience based on the topic the author is writing about and the purpose and focus of it, therefore the central ide summarizes in one sentence all the content of the text including major details. This implies, the central idea is the idea or point the author develops in during the text by organizing the information in paragraphs and including details, evidence, examples, etc. Additionally, to this, central ideas can be stated explicitly or developed implicitly and can be found in almost any types of text including literary works, scientific articles, research reports, essays, etc. as all texts generally develop one central point or idea. Thus, the statement that is not true about central ideas is that "Central Ideas are only found in literary works" because the central idea can be found in most of the texts whether they belong to literature or not.
