Directions (101-102): In each of the following questions, a sentence has been divided into four phrases. These phrases may or may not have been placed in their correct positions. Identify the correct rearrangement of the phrases to make the sentence grammatically correct and contextually meaningful, and mark that option as your answer.

shaped the world we live in today and (A)/ triumphs and tragedies, all of which have (B)/ the history of humanity is a story of (C)/ offer valuable lessons for the future (D)

To find the correct rearrangement of the sentence fragments, we can analyze the logical and grammatical connections between them:

1. Starting Fragment: Fragment (C) "the history of humanity is a story of" introduces the main subject ("the history of humanity") and verb phrase ("is a story of"). The preposition "of" at the end of (C) requires an object (a noun or noun phrase) to follow it.
2. Connecting C to B: Fragment (B) begins with "triumphs and tragedies", which serves as the perfect object for the preposition "of" in (C). Together, they form: "the history of humanity is a story of triumphs and tragedies...".
3. Connecting B to A: Fragment (B) ends with "all of which have". The helper verb "have" must be followed by a past participle to form the present perfect tense. Fragment (A) begins with "shaped" (a past participle), making it the correct continuation: "...all of which have shaped the world we live in today and".
4. Connecting A to D: Fragment (A) ends with the conjunction "and", which links the first clause to another action. Fragment (D) "offer valuable lessons for the future" starts with the verb "offer" and completes the sentence smoothly.

Combining these steps in the sequence C - B - A - D gives us a grammatically sound and meaningful sentence:
"The history of humanity is a story of triumphs and tragedies, all of which have shaped the world we live in today and offer valuable lessons for the future."
