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 documentary filmmaker chose to ____ her personal grief over her father's death into the narrative, making the film unexpectedly intimate and raw. 2. The metallurgist demonstrated how extreme pressure could ____ two dissimilar metals at the molecular level, creating an alloy stronger than either base material alone.

Sentence 1 — Needs a verb for blending grief into a narrative. To FUSE means to merge so completely that the elements become inseparable — the grief didn't just appear in the film, it became one with it, explaining the raw intimacy. Sentence 2 — Needs a precise metallurgical verb. To FUSE in materials science means to unite substances at the molecular level through heat or pressure, which is exactly the process described. Option 1 (Infuse) loosely fits S1 but has no metallurgical application in S2. Option 3 (Weld) is a metallurgical term but means surface-level joining, not molecular blending, and carries no narrative metaphor. Option 5 (Channel) works in S1 but is meaningless in S2's scientific context. Option 2 (Embed) implies insertion, not true merging — weak in both.
