Explanation
To choose the correct set of words, we must analyze the logical relationship between the two parts of the sentence.
Step 1: Analyze the first blank The sentence mentions "notions of change and stability." In Greek philosophy, these were often seen as contradictory ideas (Heraclitus argued everything changes, while Parmenides argued nothing changes).
-
When two opposing ideas are brought together to coexist logically, the verb used is reconcile.
-
"Confirm," "Simplify," or "Eliminate" do not fit the philosophical context of balancing the concepts of change and stability.
Step 2: Analyze the second blank The sentence describes the "atom."
-
Historically, the word "atom" comes from the Greek word atomos, which literally means "indivisible" (cannot be cut or divided).
-
While an atom is "interesting" or "specific," the defining characteristic postualted by Greek philosophers (like Democritus) was its indivisibility.
-
"Infinitesimal" means extremely small, which is true, but "indivisible" is the precise philosophical and historical term required here.
Step 3: Evaluate the complete sentence
"Greek philosophers tried to reconcile contemporary notions of change and stability by postulating the existence of the atom, an indivisible particle from which all varieties of matter are formed."
This makes perfect sense: the unchanging (stable) atoms move and combine to create the appearance of a changing world.
Final Answer:
The correct option is (b) reconcile..... an indivisible.
