Fill in the blanks. The boy scouts gathered in the courtyard to ______ the American flag and hoist it up the pole after unfolding it.

The sentence describes a flag ceremony, where the American flag is unfolded and hoisted. The correct verb should refer to unfolding something that was rolled or folded, which fits naturally before hoisting it up the pole. Harmonise – means to bring into agreement or harmony, especially musically or socially. Not relevant to the physical act of raising a flag. Unfurl – means to unfold or spread out something, especially a flag or sail. This word perfectly fits the context of a flag being prepared and raised. Inform – means to give information. Grammatically doesn't fit the physical nature of the action. Tie – doesn’t logically pair with "unfolding" and “hoist.” You don’t tie a flag before hoisting. Misnomer – a wrong or inaccurate name; not a verb and doesn’t make sense in this context.
