Understanding Phrasal Verb Break Open

The question asks us to find the correct meaning or substitute for the underlined phrasal verb "break open" as used in the sentence: "We had to break open the main door because the keys got misplaced by someone."

A phrasal verb is a phrase combining a verb with an adverb or preposition, or sometimes both, to create a new meaning. In this case, the verb is 'break' and the adverb is 'open'.

Meaning of 'Break Open'

The phrasal verb 'break open' typically means to force something open, often because it is locked, sealed, or difficult to open by normal means. When you 'break open' something like a door, chest, or package, you are using force to get it open, potentially damaging it in the process.

In the given sentence, the keys were misplaced, making it impossible to open the door normally. Therefore, they had to use force to open the door, which is exactly what 'break open' implies.

Analyzing the Options

Let's look at the provided options and see which one best fits the meaning of 'break open':

• Cut: To cut means to divide or separate something with a sharp instrument. This is not the meaning of 'break open' a door.
• Open with force: This option means to use physical strength or pressure to open something. This perfectly matches the meaning of 'break open', especially in the context of a locked door when keys are lost.
• Burn: To burn means to consume by fire. This is completely unrelated to opening a door.
• Sharpen: To sharpen means to make something sharp. This is irrelevant to opening a door.

Based on the analysis, the phrase that can be substituted for "break open" and conveys the same meaning in the context of the sentence is "open with force". When you need to open a door without keys, you often have to apply force, or 'break it open'.

Therefore, "open with force" is the correct substitute for the phrasal verb "break open".
