Russian troops were mobilized against Austria-Hungary because Russia believed that Germany was hiding under the guise of the assassination of Austrian Archduke Franz Ferdinand to launch a war and protect their powers in the Balkans.
The only one that is right is A. "the bird flew south of the beach" all of the other sentences should have "have" not "of".
Its neither debatable nor specific
Answer:
C. Flies
Explanation:
The correct answer is "flies" in this case. We know this is true because the sentence is in the present tense form, indicated by the verb "circling" which is the present participle tense of the infinitive "circle". We need our tense to be consistent throughout the sentence, so we use "flies" the present indicative tense of the infinitive "fly".
Hope this helped
