Final answer:
To counter objections, Cora can use past success, highlight the outdated basis of objections, cite expert support, or demonstrate the impracticality of alternatives.
Step-by-step explanation:
In a debate or discussion, countering objections effectively requires strategic thinking. If Cora wishes to rebut Bernard's rejection of her explanation, she could present new information or perspective to undermine his argument. For instance, if Cora has successfully implemented a similar solution in the past (option a), this historical precedent can serve as empirical evidence to support her explanation. Furthermore, if Bernard's objections are found to be based on outdated information (option b), implying that Cora's proposal is more current and therefore potentially more valid, this can erode the credibility of Bernard's stance. Additionally, presenting support from experts in the field (option c) who endorse Cora's explanation can bolster her position through an appeal to authority. Lastly, if Bernard's alternative is impractical (option d), Cora can argue that her solution is the more feasible option. Each of these tactics aims to weaken Bernard's rejection by offering concrete reasons as to why Cora's explanation remains formidable despite his critiques.
