Question

Select the most appropriate option to substitute the underlined segment in the given sentence: Charles Darwin is renowned for his book on evolution, ‘On the Origin of Species’, which laid down a treasure of substantiation that evolution occurs, and projected a mechanism, that is, natural selection, for how it does so.

Underlined segment: laid down a treasure of substantiation

Accepted Answer

The phrase 'laid down a treasure of substantiation' is incorrect because 'laid down' does not collocate properly with 'a treasure of substantiation'. The correct idiomatic expression is 'laid out', which means to present or explain something clearly and in detail. Hence, 'laid out a treasure of substantiation' is the most appropriate substitution. The other options ('laid into', 'laid about', 'laid away') are either incorrect idiomatic uses or do not fit the context.
