In each of the following questions, select the option that best completes the gap. The touts ____ arrested during the riot.

To determine the correct word to fill in the blank, let's analyze the sentence structure and the options given:

The subject of the sentence is "touts." The word "touts" is a plural noun, meaning it refers to more than one person. Therefore, any verb that accompanies it must also agree with its plural form.

Let's examine the options:

• "were" - This is the past tense form of the verb "to be" that is used with plural nouns. E.g., "They were happy."
• "was" - This is the past tense form of the verb "to be" used with singular nouns or singular third-person subjects. E.g., "He was happy."
• "where" - This is used to indicate a place or position, not a verb.
• "is" - This is the present tense singular form of the verb "to be" and does not match the past tense context of the sentence.

Based on the analysis, the most suitable option is "were." The sentence should read: "The touts were arrested during the riot." This fits because "were" is the correct past tense form of the verb "to be" for plural subjects. The use of "were" indicates that the action occurred in the past, and it agrees with the plural noun "touts."
