In each question below, two sentences are given with one blank each. Choose the option which contains the word that fits in both sentences, making them grammatically and contextually correct. 1. The philosopher argued that modern society's obsession with productivity had reduced human beings to mere ____ in a vast economic machine. 2. The watchmaker held up the tiny ____ and explained how the failure of this single component had caused the entire mechanism to seize.

Sentence 1 — Needs a noun functioning as a philosophical metaphor. COGS — as in cogs in a machine — is a classic metaphor for individuals stripped of autonomy and reduced to interchangeable parts in an economic system. Sentence 2 — Needs a literal mechanical term. A COG is a tooth on a gear or a small gear itself — a real watchmaking component whose failure can stop an entire mechanism. Option 1 (Components) works in S2 but is too generic to carry the critical philosophical weight in S1. Option 4 (Instruments) implies agency, which directly contradicts S1's dehumanizing argument. Options 2 & 5 fit neither sentence with precision.
