American stick sculptor and artist Patrick Dougherty is famous for his stunning art installations made from natural materials. His work, woven out of living, growing trees, is praised for its environmental consciousness, as the materials are biodegradable and sustainable, leaving no impact on the environment.Choice A is the best answer. The convention being tested is subject-verb agreement. The singular verb “is” agrees in number with the singular subject “His work.”
Choices B, C, and D: The plural verbs “were,” “have been,” and “are” do not agree in number with the singular subject “His work.”
✨ Expert's Tip ✨
- When the answer choices are verbs, be sure to first check out their agreement in number with the subject.
- It is smart to trim the sentence by crossing out the modifiers like prepositional phrases or words set off by commas.
