Final Answer:
Tim threatens to shoot his brother Sam because Sam joined the British army.Thus the option c) Sam joined the British army is correct.
Step-by-step explanation:
Threatening to shoot someone is a serious matter and should not be taken lightly. In this scenario, the most likely reason for Tim's threat is that Sam joined the British army (option c). Joining the military of another country, especially during times of conflict, can evoke strong emotions and lead to intense reactions from family members.
Tim's threat may stem from a mix of fear for Sam's safety, disagreement with Sam's decision, and heightened emotions associated with the complexities of armed conflicts.
Firstly, joining a foreign military may be perceived as a betrayal of loyalty or a threat to familial bonds, contributing to Tim's extreme reaction. Secondly, the historical context could play a role, as joining the British army might be seen as aligning with an opposing force, causing Tim to feel a sense of betrayal or anger.
Lastly, the threat may be an expression of Tim's concern for Sam's safety, as military service often involves risks and challenges that can be distressing for loved ones.
In conclusion, the choice of option c reflects the plausible explanation that Tim's threat is linked to Sam's decision to join the British army. This answer takes into account the emotional and familial dynamics involved in such a scenario, emphasizing the complexity of human relationships in the context of significant life choices.
Thus the option c) Sam joined the British army is correct.
