If the train is delayed, we will have to _________ our travel plans accordingly.
The sentence suggests changing plans due to delay.
- "Adjust" means to modify or change to suit new conditions, which fits perfectly.
- "Abandon" means to give up entirely, stronger than needed here.
- "Cancel" means to call off plans, which is possible but less flexible.
- "Oppose" means to resist or go against, which is illogical in this context. Hence, "adjust" is the best choice.
