Final answer:
Individuals are least likely to end a relationship if a partner snores. Other options like forgetting birthdays or unemployment might lead to higher conflict due to perceived neglect or financial strain.
Step-by-step explanation:
If faced with the situation described, individuals are least likely to end a relationship with someone if they snore. Snoring is a common issue that many people deal with and can often be addressed with various remedies or medical assistance. In contrast, forgetting a birthday or leaving dirty dishes might be seen as indicative of neglect or disrespect, and losing a job can bring significant financial stress to a relationship, all of which might be seen as more serious issues. Remember that the strength and commitment of a relationship can also play a significant role in how such issues are perceived and dealt with.
