Understanding the argument - The Republic of Estonia is separated from Finland by the narrow Gulf of Finland. - Fact.
The Estonian people are genetically similar to the Finnish people. - Fact.
Estonians also speak a language that is very closely related to Finnish. - Fact
It is likely that, many centuries ago, residents of what is now Estonia migrated to what is now Finland and established settlements there. - Conclusion
Which of the following, if true, does the least to undermine the Author's explanation for the similarities given?
Option Elimination - 4 weaken except 1, which could be anything - strengthener, out of scope, distortion, etc., but weakener.
A. The earliest settlements found in Finland exhibit cultural influences common to Estonians and Finns predate the earliest settlements found in Estonia that exhibit these traits. - Means the opposite relationship - Finland to Estonia.
Weaken. B. At the time when the residents of present day Estonia are believed to have migrated to present day Finland, travel by boat across the Gulf of Finland was impossible. - Weaken.
C. Early Estonian artifacts contain drawings of animals that were native only to Finland at the time the migration was believed to have taken place. - Shows Finland was established, and movement occurred from Finland to Estonia. - This option opens the possibility of a more nuanced relationship than just the unidirectional movement from Estonia to Finland, direction of relationship that is stated in the conclusion.
With this option,
a. Estonians may have traveled to Finland and brought back the artifacts.
b. Finnish may have traveled to Estonia and brought these artifacts
c. There was a bidirectional relationship between Finland and Estonia.
This option plays with our thought process. We assume that to be a weakener, it has to SHATTER the conclusion, meaning the magnitude of impact is grand. GMAT knows our weakness so instead of giving an option that'll satisfy our wrong belief, it gives a weak weakner. Remember, a weakener or strengthen has to move a needle, in distance terms it can be one millions of 1 mm, but that is still a movement or a weakner or strengthener. So, always look for the direction of impact (positive or negative) and then look for magnitude. Strengthen and Weaken work on the direction rather than necessarily on the magnitude, while we focus on magnitude first, a mindset that will not help us eliminate this option. Weak weakener.
D. The traits common to the people of Finland and Estonia are also shared by the population of present-day Sweden. - Still, the conclusion can be valid. Sweden to Estonia to Finland. While option C casts doubt on the one-way movement, this option still makes it possible for the conclusions to stay valid. Ok.
E. The Norwegian people are more similar to the Finnish people than are Estonians. - Weakener
