When a patient is suspected of having a concussion, or brain injury, doctors often turn to computed tomography, or CT, scans to find out for sure. In a CT scan, a series of X-rays is taken. Each one shows an individual "slice" of the brain, and they can be combined to form a complete three-dimensional picture. Because of the amount of radiation patients are exposed to, however, doctors question the use of the scans, especially for children. Now researchers have proposed an alternative way of diagnosing head injuries: a simple blood test. The test detects proteins that burst out of brain cells into the bloodstream immediately after an injury. It allows doctors to determine whether a patient has suffered head trauma and needs further treatment. What is the main idea of the passage?

the words "strangest" and "unusual" suggest (:

hello!

"hidesato showed not the least sign of fear. he tried to calm the dragon king: don't be afraid. i shall surely kill the centipede."

hope this .

first of all the mood needs to be defined: it is obviously a mood of deceitful relief and serenity. why? because the cape horn is one of the most violent maritime regions of earth and although it has been left behind, it is a personification of ahab’s delirium and the fact that the end of the passage speaks about it about being “hidden” but “raving” immediately conveys the feeling the calm is not permanent but fleeting.

furthermore, the oxymoron “mild stun'sails” is the first instance of such feeling as the adjective “mild” is associated with “stunned” underscoring the fleeting nature of this “tranquil” moment. and the contrasts keep piling up, with the opposition between “dark den” and “blessed light and air” to end with the final conclusion that leaves the reader with the uneasy knowledge that this is just a reprieve.

1. an introductory word, phrase, or clause which is missing the word(s) it is supposed to modify- dangling modifier

words, clauses or phrases which add description is known as a modifier. a modifier is found before or after the target words that they want to describe.

for example: happily, she ran towards her father.

herein, happily precedes 'she', its target.

whereas, when an author forgets to mention the target and includes the modifier thus it is known as a dangling modifier, wherein modifier has nothing to describe. these are the errors which confuse the reader.

2. a noun or pronoun's function within a sentence- elliptical clause

it is a clause in which words are being left out. on the other hand, the missing word is understood due to the logic or pattern of the sentence.

for example:

she had five apples;   kanishk, three.

herein the verb 'had' is missing which is otherwise understood.

3. to quickly run: split infinitive

it refers to the construction of the sentence in which infinitive consists with the word or an adverb between to and verb.

for example, he used to secretly ate those apples.

4. a clause with either an implied subject or verb: elliptical clause

5. a word that joins words or phrases of the same grammatical type: coordinating conjunctions are the words which connect clauses and phrases. there are seven coordinating conjunctions that are, yet, so, or, for, and, nor, and but.

for example:

the boy refused to complete the homework nor will he take the punishment.

'and' is the coordinating conjunction.

7. pronoun with no specific antecedent: indefinite pronouns are the pronouns which do not refer to anyone specifically.

for example several, nobody, some and so forth.

8. a pair of words like either/or: correlative conjunctions

these are the pairs of conjunctions used in a sentence to join elements together. these are, , not also, and so forth.

9. masculine and feminine forms: gender

gender refers to the cultural, psychological and behavioral traits that are associated with a particular sex.
