Select the most appropriate option that can substitute the underlined segment in the given sentence.
Alternative animal feeds can be source from byproducts, waste streams or novel crops; they are all designed to facilitate more sustainable agriculture.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option B i.e. can be sourced from.
Error concept: Passive voice construction with correct verb form.
What is wrong: The original phrase “can be source from” is grammatically incorrect because “source” should be in past participle form.
Grammatical concept: In passive voice, we use “be + past participle” after modal verbs like can.
Incorrectness of the concept in context: “source” is a base verb here, but passive requires sourced.
How to correct: Change source to sourced.
Correction: can be sourced from
Final sentence: Alternative animal feeds can be sourced from byproducts, waste streams or novel crops; they are all designed to facilitate more sustainable agriculture.
Hence, the chosen option is correct.
