Blank Word Explanation

The question asks us to select the most appropriate word to fill in the blank in the sentence: "_________ the flying bricks and bottles, the riot police kept calm." This sentence describes a situation where police maintained their composure despite facing dangerous objects being thrown at them during a riot.

We need a word that signifies being in the middle of or surrounded by a chaotic or difficult situation.

Analyzing the Options

Let's look at each option:

• about: This preposition usually indicates a topic or approximation. For example, "The book is about history." It doesn't fit the context of being physically surrounded by flying objects.
• beside: This preposition means next to or alongside something. For example, "The chair is beside the table." This doesn't convey the sense of being in the midst of a chaotic event.
• until: This word indicates a time limit. For example, "We waited until midnight." It doesn't relate to the spatial or situational context of the sentence.
• amid: This preposition means in the middle of, or surrounded by (something considered confusing or difficult). For example, "He remained calm amid the chaos." This perfectly describes the situation where the police are in the middle of flying bricks and bottles but remain calm.

Choosing the Correct Word

Based on the analysis, the word amid is the most suitable choice because it accurately reflects the context of the riot police being in the middle of flying projectiles while maintaining their calm demeanor.

Therefore, the completed sentence reads: "Amid the flying bricks and bottles, the riot police kept calm."
