#### IR + CR two-part analysis: archaeologist and porcelain

Mon Jun 24, 2013 11:18 pm

----

Archaeologist: There were several porcelain-producing centers in 18th-century Britain, among them Bristol, Plymouth, and New Hall. Each center developed a unique recipe for its porcelain that might include flint glass, soapstone, bone ash, clay, quartz, and so on. We will therefore be able to determine, on the basis of compositional analysis, where the next cup we recover from this archaeological site was made.

Indicate two different statements as follows: one statement identifies an assumption required by the archaeologist's argument and the other identifies a possible fact that, if true, would, provide significant logical support for the required assumption.

A. Other cups have been recovered from the archaeological site, all of which were made of porcelain.
B. Some of the cups recovered from the archaeological site were not made of porcelain.
C. The next cup to be recovered from the site will likely be made of porcelain.
D. Porcelain makers often traveled between centers, experimenting with one another's recipes.
E. There was considerable overlap of materials in recipes used by the various centers.
F. Most porcelain in 18th-century Britain was made at one of the several centers.

----

The prompt asked us to identify assumption required and possible fact that would support the required assumption.

I understood the assumption part, but the "possible part" fact confused me.

Why is answer choice A a better choice than answer choice F? Both answer choices are good strengtheners, but why is one answer choice correct and the other is wrong?

The option 'A' is better than 'F' due to 2 reasons:

1. 'A' refers to "other cups" since the question also says "where the next cup we recover from". 'F' only refers to most porcelain.

2. 'A' says that all of which were made of porcelain. 'F' says most porcelain was made at one of the several centers.

Hope that helps!
