Final answer:
The sentence has a pronoun reference error, as it's not explicitly explained 'it' refers to 'her proposal'. This ambiguity can be avoided by rewriting the sentence.
Step-by-step explanation:
The sentence 'Jenny worked hard on her proposal, and it deserves my undivided attention.' does not have an explicit grammatical error. However, an ambiguity arises due to the unclear antecedent of the pronoun 'it'. The type of error here is a pronoun reference error. Although it's likely that 'it' refers to 'her proposal', it's generally best to avoid such ambiguities in academic and professional writing. Instead, we could rewrite the sentence as: 'Jenny worked hard on her proposal, which deserves my undivided attention.' to be clearer.
The error in the sentence is a pronoun error. The pronoun 'it' is used to refer to 'proposal', but the pronoun should agree in number with the antecedent. Since 'proposal' is singular, the pronoun should be 'it's' rather than 'they deserve'.
A correct version of the sentence would be: 'Jenny worked hard on her proposal, and it deserves my undivided attention.' In this version, the singular pronoun 'it' matches the singular noun 'proposal'.
