Resist the urge to be purely emotional. The medical-necessity argument (vaccines, life-saving drugs) is strong; the ethics argument (sentience, suffering, alternatives like organ-on-a-chip technology) is equally strong. Your opinion should chart a middle course.

How to crack it
A 5-step plan for the essay
Read the question twice.
Underline every keyword. The instruction word ("agree", "discuss") decides your structure. Get this wrong and you cap at 5.
Plan for 5 minutes.
Two body paragraphs. One main idea each. Pick examples BEFORE you write the intro.
Write your intro last in your head.
Once you know the conclusion, the intro writes itself. Paraphrase the question, don’t copy it.
Aim for 270–290 words.
Less = task incomplete. More = grammar errors. Stay in the pocket.
Leave 3 minutes to proofread.
Hunt articles ("a/an/the"), subject-verb agreement, and "make/do" mix-ups. They’re your usual suspects.
What loses you the band
The four traps this question sets
Off-topic intro
Paraphrase the question. Don’t broaden it.
Conclusion that just repeats
Add one new reason. Or a recommendation.
"Make a damage"
Collocation slip. Use "cause damage".
"Furthermore. Moreover."
Pick one. Both = robotic.
