Replace the underlined portion with the answer choice that results in a sentence that is clear, precise, and meets the requirements of standard written English.
The detective was an expert in these kinds of cases, always called on when the force needed expert advice.
and was called on when the force needed expert advice.
always called on when the force needed expert advice.
always call on when the force needed expert advice.
always calling on when the force needed expert advice.
always called on when the force needs expert advice.
The underlined portion of the phrase is a dependent clause that is confusing because of the way it is worded. The phrase needs to be better linked to the main portion of the sentence. The answer choice which best does this is "and was called on when the force needed expert advice."
Replace the underlined portion with the answer choice that results in a sentence that is clear, precise, and meets the requirements of standard written English.

The original sentence is a fragment. Read it out loud, and it will probably sound like it is missing something. To fix this, change the verb “being” to “is.” This is more direct and fixes the fragment issue. The other choices either don’t fix “being” or add unnecessary progressive verbs (i.e. "is not having").

In its current state, this is a run-on sentence because it has two independent clauses that are not joined with a conjunction or semicolon. In this answer choice, the appropriate conjunction is added to the introductory clause, making the introductory clause dependent and the sentence grammatically correct.
Replace the underlined portion with the answer choice that results in a sentence that is clear, precise, and meets the requirements of standard written English. One of the answer choices reproduces the underlined portion as it is written in the sentence.
The researchers found that humans can detect millions of different odors, dogs, in contrast, can detect only a few thousand.
detect millions of different odors; dogs, in contrast, can detect only a few thousand
detect millions of different odors; whereas dogs, in contrast, can detect only a few thousand
detect millions of different odors; and dogs, in contrast, can detect only a few thousand
detect millions of different odors, dogs can detect only a few thousand in contrast
detect millions of different odors, dogs, in contrast, can detect only a few thousand
The original text contains a run-on sentence. That means that the original text places two complete sentences side by side, separated only by a comma. Answer choice "detect millions of different odors, dogs can detect only a few thousand in contrast" also results in a run-on sentence.
To fix a run-on sentence, you can either change the comma to a semicolon, as in answer choice "detect millions of different odors; dogs, in contrast, can detect only a few thousand," or you can insert a conjunction after the comma.
Answer choices "detect millions of different odors; whereas dogs, in contrast, can detect only a few thousand" and "detect millions of different odors; and dogs, in contrast, can detect only a few thousand" are incorrect because they make both of these changes—changing the comma to a semicolon and inserting a conjunction— instead of just one or the other.

The sentence is a compound sentence, or one sentence that contains two complete thoughts joined together to highlight their relationship to each other. All compound sentences must be joined either by a semicolon or a comma and a conjunction.

Statistics are not always a reliable source of information, many data are tailored to suit a person’s agenda.
information; many data are
information: many data are
information, many data is
information; many data is
information, many data are
A semicolon is an appropriate punctuation mark to use when separating two full sentences that are closely related, though this separation can also be accomplished with a comma followed by a conjunction. Although the word data does not end in “s,” it is actually plural, so “many data are" is correct.
