steel containing element X= stronger and more flexible than ordinary steel.
reason= X reduces the occurrences of microscopic fractures.
steel produced in canada- naturally high element of X.
Reason= ore deposits used to produce also contain X.
A this is comparing steels strength and flexibility between canada and other country. we dont anything about the other country's steel. so we cant make that inferences here, out.
B we cant say that steel from other countries can develop high microscopic fractures after years of use. out.
C we cant claim what is the best way of making the steel more stronger and flexible.
D yes. if we use researches claim and combine with properties of steel being produced in canada from ore, then we can say that some steel are less likely to develop microscopic fracture.
E what we know from passage was that canadian steel made from ore deposit has naturally high X but that doesnt mean it has the highest level found in any steel. thats too extreme here.
ans D

A researcher has discovered that steel containing Element X is stronger and more flexible than ordinary steel because Element X reduces the occurrence of microscopic fractures. The level of Element X in much of the steel produced in Canada is naturally high because the ore deposits from which the steel is produced also contain Element X.
Which of the following can be correctly inferred from the statements above?
A. Steel from Canada is stronger and more flexible than steel from any other country.
B. Steel that is not from Canada is highly likely to develop microscopic fractures after years of use.
C. Producing steel from ore deposits containing Element X is the best way to make steel that is stronger and more flexible.
D. Some steel produced in Canada is less likely to develop microscopic fractures than other steel.
E. Steel produced from Canadian ore deposits contains the highest levels of Element X found in any steel.
