Answer:
The world would be better off without cockroaches. Cockroaches carry disease and can trigger allergies or asthma attacks.
Step-by-step explanation:
"Cockroaches carry disease and can trigger allergies or asthma attacks" best sopports the claim "the world would be better off without cockroaches." This is because the claim is going against cockroaches saying the world would be better off without them and the sopport gives reasons on why. If you chose the second sentence as the sopport then you would be wrong because the sentence is supposed to sopport the claim sentence but in this case it goes against the claim, saying "the world would be better off without cockroaches. Cockroaches are an important part of forest ecosyste,s since they regulate nitrogen, allowing plants to grow." See it doesn't make sense and the reason is that the supporting sentence doesn't sopport the claim. Which is why the sentence "the world would be better off without cockroaches. Cockroaches carry disease and can trigger allergies or asthma attacks," is correct.
