A framework for understanding how habits work and a guide to experimenting with how they __________ change. Some habits yield easily to analysis and influence. Others are __________ complex and obstinate, and require prolonged study.
- Amight
- Bwould
- Cwill
- Dmust
Explanation
'How they might change' — 'might' expresses possibility, which is the sense required (habits may possibly change). 'Must' would express necessity, 'may' is close but the past-tense-frame answer keyed is 'might', and 'would' expresses conditionality. Hence (A) might is correct.
