CR, Chapter 1 In-Action Q4

The fossils found in the Burgess Shale, an area high in the Canadian Rockies, are especially valuable to evolutionary science. Due to the unique geological conditions of the region, the fossils include appendages and soft parts that are rarely preserved. By studying these remains, scientists are offered insights into the precursors of contemporary life forms.

The answer key indicates that the first sentence is the conclusion. However, it seems to be a statement of fact, rather than a claim that is contestable. Additionally, the usual indicative words “i.e. should, might” are absent.

Any extra guidance would be appreciated. Thanks
:wink:

the statement is a value judgment, or, equivalently, a statement of opinion. such statements are, by definition, claims.

the only exception would occur in a case where you set down strict definitions of terms that are normally matters of opinion (such as "i'll call something 'expensive' if its fair market value is exactly $5,414.12 or greater"). that doesn't happen here, so the first statement is a pure value judgment, and, as such, is a claim.

you can also use the THEREFORE TEST to figure out which statement is the conclusion. the only other reasonable contender is the final statement, so duke it out with those two statements:

By studying these remains, scientists are offered insights into the precursors of contemporary life forms; therefore The fossils found in the Burgess Shale, an area high in the Canadian Rockies, are especially valuable to evolutionary science --> makes total sense

The fossils found in the Burgess Shale, an area high in the Canadian Rockies, are especially valuable to evolutionary science therefore By studying these remains, scientists are offered insights into the precursors of contemporary life forms --> makes no sense



wink?
