Cevap

grows sharp spines to deter herbivores.
The sentence presents a list of three actions that share the subject pronoun 'it'. The first two actions are expressed as active present-tense verbs ('stores' and 'absorbs'). To maintain parallel structure, the third action must also begin with an active present-tense verb. The phrase 'grows sharp spines to deter herbivores' conforms to this structure, making the sentence grammatically correct.

Adım Adım Çözüm

1
Analyze the sentence structure and locate the list of items.
The sentence lists adaptations of the saguaro cactus: 'it stores water in its thick stem, absorbs sudden rainfall with a shallow root system, and [blank]'.
This identifies the list context where parallel structure must be maintained.
2
Determine the grammatical form of the existing items in the list.
The first item starts with 'stores' (a present-tense verb), and the second starts with 'absorbs' (a present-tense verb). Both share the subject pronoun 'it'.
This establishes the grammatical pattern that the final list item must follow.
3
Evaluate the choices to find the one that matches this present-tense verb pattern.
The option 'grows sharp spines to deter herbivores' starts with a present-tense verb 'grows', completing the parallel sequence.
Choosing this option ensures standard English parallelism conventions are followed.
