By themselves presidents could never gain detailed knowledge of all the departments of government, they must rely on their advisers these advisers are members of the white house staff, they are members of the cabinet. a. fragment b. run-on c. correct

The correct answer is b) Run-on sentence

Explanation:

Run-on sentences occur when two or more independant sentences are not joined by a conjunction, semicolon or period.

In this case, the run-on sentence is "they must rely on their advisers these advisers are members of the White House staff"

"They must rely on their advisers" is an independant clause as well as " these advisers are members of the White House staff..." but they are not properly joined. In order to avoid run-on sentence, a semicolon, conjunction or period can be used.

the answer is both an appeal to ethos and logos (if that's what your question options were)
