It can be real number as well. For e.g. square root of 2 is 1.4xx . So the way I approached is that as we know 5th root of w,...

Can someone please explain? I feel that B should be the answer ( this oiption came to my mind before looking at the options) Initially you'll think why not plant both. But the farmers would go for Spring crops as they need to be planted before the Winter wheat can be harvested. If the farmer goes wi...

OK so in that case doesn't E actually support the Skeptic's claims. It shows a limitation of X-Ray machine thereby supporting the Skeptic's claims that "that X-ray examinations of the Mona Lisa do not show hidden mountains." .
How does it weaken Skeptic's claims?
