本题考查对英文单词词义的掌握。解题思路是明确题干中给出的中文释义，然后依次分析每个选项单词的含义，找出与题干释义匹配的选项。

• 选项A：“calculation”的读音为 /ˌkælkjəˈleɪʃn/，其英文释义为“the process of using numbers to find an amount or answer; the result of this process” ，中文释义为“计算；估计；计算的结果” ，与题干中“计算；估计；计算的结果；深思熟虑”的释义相符。
• 选项B：“commission”读音为 /kəˈmɪʃn/，英文释义为“an amount of money that is paid to someone for selling something, especially a percentage of the total price; a group of people who are officially chosen to do a particular job”，中文释义为“佣金；回扣；委员会；委托”，与题干释义不匹配。
• 选项C：“currently”读音为 /ˈkʌrəntli/，英文释义为“at the present time; now”，中文释义为“目前；当前”，与题干释义不相符。
• 选项D：“cognitive”读音为 /ˈkɒɡnətɪv/，英文释义为“relating to the mental process of knowing, including aspects such as perception, memory, and judgment”，中文释义为“认知的；认识的”，与题干释义不一致。
