Problem: Given the question: Extract the answer to the question from the following context. Question: What does the lack of universally accepted criterion for distinguishing between a language or a dialect cause? Context: There is no universally accepted criterion for distinguishing two different languages from two dialects (i.e. varieties) of the same language. A number of rough measures exist, sometimes leading to contradictory results. The distinction is therefore subjective and depends on the user's frame of reference. For example, there is discussion about if the Limón Creole English must be considered as "a kind" of English or a different language. This creole is spoken in the Caribbean coast of Costa Rica (Central America) by descendant of Jamaican people. The position that Costa Rican linguists support depends on the University they belong.

The answer is:
contradictory results


Problem: Given the question: Extract the answer to the question from the following context. Question: What is a servo system first compared to? Context: A servo system differs from some stepper motor applications in that the position feedback is continuous while the motor is running; a stepper system relies on the motor not to "miss steps" for short term accuracy, although a stepper system may include a "home" switch or other element to provide long-term stability of control. For instance, when a typical dot matrix computer printer starts up, its controller makes the print head stepper motor drive to its left-hand limit, where a position sensor defines home position and stops stepping. As long as power is on, a bidirectional counter in the printer's microprocessor keeps track of print-head position.

The answer is:
some stepper motor applications
