Question

erratic means :

• lacking zest or vivacity
• having no fixed course
• serving or tending to provoke, excite, or stimulate
• joyously unrestrained

Explanation:

To solve this, we analyze the meaning of "erratic". "Erratic" refers to something that is irregular, unpredictable, or has no fixed path/course. Let's check each option:

• "lacking zest or vivacity" describes something dull, not erratic.
• "having no fixed course" matches the definition of erratic (e.g., erratic movement has no fixed path).
• "serving or tending to provoke, excite, or stimulate" is about provoking, not erratic.
• "joyously unrestrained" is about being joyful and unrestrained, not erratic.

Answer:

B. having no fixed course (assuming the second option is labeled B; if the original labels were different, adjust the label but keep the text. Since the options are presented with the second one as "having no fixed course", that's the correct choice.)
