Final answer:
Teachable abilities that can be easily measured, such as speaking multiple languages, are referred to as tangible skills, which are distinct from concepts like emotional intelligence, intuition, or intrinsic motivation.
Step-by-step explanation:
Teachable abilities that are easy to measure, such as speaking multiple languages, fall under the category of tangible skills. These are concrete skills that you can teach, learn, and evaluate through observation and measurement. In contrast, elements such as emotional intelligence involve understanding and managing one's own emotions and the emotions of others, which are less easily quantified.
Looking at the options provided for teachable abilities: Intuition is a gut feeling or a non-conscious process, not easily measured or taught. Intrinsic motivation refers to doing something for its own sake and personal reward, which is internal and not a teachable skill. Tangible skills are the abilities that can be taught and measured, fitting the description in the question. Finally, emotional intelligence involves recognizing and managing emotions, which is also not typically considered a teachable skill in the same way as language fluency.
