Hi. You forgot to say that this question is about the "Blood, Toil, Tears, Sweat" speech.
Answer and Explanation:
Britain is facing World War II and that war is the "rigor of events" that Churchill is referring to. Students should demonstrate that Churchill addresses the issues related to war in the aforementioned speech, when it shows the urgency of appointing him as prime minister, the urgency to appoint members of parliament as soon as possible and the responsibility he has assumed, stating that he would offer his full work and even his blood to run the country efficiently at such an important time.
If students present this type of argument it will show that they have prepared for the discussion, read the speech and interpreted it according to the historical context that it has.
