Although the two research teams agreed on the single fossil's age, they disagreed on the specimens' origin and it's classification within the dinosaur family tree.
Which choice most effectively and grammatically completes the underlined portion of the sentence?
- Aspecimens' origin and it's
- specimen's origin and itsAnswer
- Cspecimen's origin and it's
- Dspecimens' origin and its
Answer
specimen's origin and its
The correct option correctly uses the singular possessive noun 'specimen's' because the context refers to a single fossil. It also correctly uses the possessive pronoun 'its' to show that the classification belongs to the specimen, avoiding the contraction 'it's' (which means 'it is').
