Final answer:
The word that best describes moving left, then right, back to the left, and right again is 'zigzag', which reflects the sharp, angular path of such movement. The other options provided, such as 'meander', 'traverse', and 'oscillate' have different meanings and do not specifically describe the motion pattern of the main question.
Step-by-step explanation:
The term that best describes the motion of going to the left, then to the right, back left, and right again is zigzag. This pattern reflects the sharp, angular path that one would take if they were to move in such a manner. The word zigzag implies a series of turns or changes in direction, which aligns with the movement described in the question.
In regard to the options provided:
- (a) Zigzag - This is the correct answer as it represents sharp, back and forth changes in direction.
- (b) Meander - Implies a more gentle, winding path.
- (c) Traverse - Means to move across an area, which could imply a direct or indirect path, but not specifically the left-right-left-right motion described.
- (d) Oscillate - Refers to moving back and forth in a steady rhythm, typically within a fixed area, which doesn't necessarily include the directional changes of zigzagging.
The other information provided in the question details various other English language exercises that help students understand the spelling and usage of certain terms and does not apply to the main question about movement direction.
