<em>"If the inference is proven wrong by any statements in the paragraph, it is not useful inference"</em>. This is not true. The inference is not done on the basis of the single sentence. There are other sentences which concludes the inferences and thus one wrong sentence cannot illustrate and depict the entire inference wrong. There are various facts and figures which helps in the inference and the important conclusions.
It’s True because if the inference you’ve stated contradicts itself then it’s not useful inference. Inference is when you can state something that isn’t obvious in the text given.
