Today's Practice GMAT Question:
|
Geologist: The element tantalum, which originates as a mineral ore known as coltan, is used as a capacitor in computers and cell phones. Most tantalum is exported by Canada, China, South America, and Australia. However, a small percentage of the world supply comes from poorly governed or conflict-torn regions of Africa and is mined using objectionable practices such as child labor. A group of scientists has begun working on a method that I believe will be able to detect chemical signatures that can distinguish tantalum samples according to their location of origin. Their technique needs to be further developed into a standardized and widely reproducible method of testing. If such testing becomes standard use among manufacturers and suppliers, it would allow companies and consumers a way to sanction human rights abuses through the marketplace. In the geologist's argument, the two portions in boldface play which of the following roles? |
|
| (A) | The first presents a circumstance for which the geologist offers an explanation; the second is part of that explanation. |
| (B) | The first acknowledges a consideration that weighs against the conclusion of the argument; the second is that conclusion. |
| (C) | The first acknowledges a consideration that weighs against the conclusion of the argument; the second provides evidence in support of that conclusion. |
| (D) | The first provides evidence in support of the conclusion of the argument; the second acknowledges a consideration that weighs against that conclusion. |
| (E) | The first is a judgment advanced in support of the conclusion of the argument; the second is that conclusion. |
