Answer :
To complete the sentences with the correct words, let's understand the context of each sentence.
The first sentence is: 'Don't leave your bicycle unlocked because someone will steal it.' In this sentence, 'steal' is the correct verb because it means to take something that does not belong to you, typically without the owner knowing, which fits the context of someone taking an unlocked bicycle.
The second sentence is: 'The police will ... someone if they're sure the person is guilty.' The word we need to find should relate to the action police take when they are confident a person has committed a crime. The correct word here is 'arrest.' To 'arrest' means to use the legal authority to take someone into custody, which is what police officers do when they believe someone is guilty of a crime.
So, the completed sentence would read: 'The police will arrest someone if they're sure the person is guilty.'
By choosing the words 'steal' for the first sentence and 'arrest' for the second, the sentences maintain logical and grammatical accuracy, ensuring they convey the intended meaning clearly and effectively.
