In the following question, a sentence is given with a part in bold. The given phrase in bold may contain an error. The options following can replace the incorrect phrase. The correct phrase that is to be replaced will be your answer. If the sentence is correct as it is, then select ‘No improvement required’ as the answer.

Despite the heavy rain, the outdoor festival continued with its plan to hosted a wide range of activity for attendees.

The correct option is host a wide range of activities.

Step-by-Step Explanation:

1. Grammar Rule - Infinitive Construction:
The phrase "plan to" requires a base form of the verb (an infinitive) after the preposition "to". Therefore, "to hosted" is grammatically incorrect. It should be "to host".

2. Grammar Rule - Noun Plurality:
The phrase "a wide range of" implies selection or variety from multiple items. Therefore, it must be followed by a plural noun ("activities") rather than a singular noun ("activity"). Furthermore, the word "range" should remain singular ("a wide range of"), not plural ("ranges").

3. Evaluating the Options:
• "hosting a wide range of activities": Incorrect because "plan to hosting" uses a gerund instead of the base verb after "to".
• "host a wide ranges of activities": Incorrect because "a" conflicts with the plural "ranges".
• "host a wide range of activities": Correct because it uses the base verb "host", the singular noun "range", and the plural noun "activities".

Thus, the correct and improved sentence is:
"Despite the heavy rain, the outdoor festival continued with its plan to host a wide range of activities for attendees."
