For millenia,mathematicians have 1.(weighed,measured,estimated,calculated) progress in terms of what they can demonstrate through proofs-that is,a series of logical steps leading from a set of axioms to an 2.(irreparable,irretrievable,irrepressible,irrefut able) conclusion.Now the doubts riddling human thought have finally infected mathematics.Mathematicians may at last be forced to accept what many scientist already have 3.(agreed,admitted,confessed,consented):their assertions are,at best,only provisionally true,true until proved false.This uncertainty 4.(dates back,rises,originates.stems),in part,from the growing complexity of mathematics.Proofs are often so long and complicated that they are difficult to evaluate.Wiles's demonstration 5.(runs,leaps,rides,flows) to 200 pages,and experts estimate it could be five times longer if he spelled out all its elements.One observer asserted that only one tenth of 1 per cent of the mathematics community was qualified to evaluate the proof.
My answers:1-weighed: 2-irrefutable; 3-admitted; 4-stems; 5-leaps
