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.

Detailed Explanation:

Let's analyze the bold phrase in the given sentence: "continued with its plan to hosted a wide range of activity for attendees."

1. Infinitive Verb Rule (to + base form):
The preposition "to" following the word "plan" forms an infinitive verb phrase. The rule for infinitives requires the base form of the verb (v1). Therefore, "to hosted" is grammatically incorrect and should be corrected to "to host".

2. Noun Form (Singular vs. Plural):
The phrase "a wide range of" refers to a variety of multiple items or events. Thus, it must be followed by a plural countable noun. "Activity" (singular) should be replaced with its plural form, "activities".

Combining both corrections gives the phrase: "host a wide range of activities".

Corrected Sentence:
Despite the heavy rain, the outdoor festival continued with its plan to host a wide range of activities for attendees.
