Critical Reasoning (CR) | Re: Last year a global disturbance of weather patterns disrupted harvests

IMO this is a bad question. Option A, if anything, is a weakener and not a strengthener. The conclusion says bad weather (cause) is responsible for higher soya bean prices (effect). It's a classic causal reasoning argument.

Which means that the effect (higher prices) is attributable to an ALTERNATIVE cause and not to the bad weather.
