1.D
【句意】约翰不是任意地挑选的，他是因为最有经验而被选做这项工作。
【解析】副词词义辨析。deliberately“故意地；慎重地”；alternatively“非此即彼；二者择一地”；momentously“重大地”；arbitrarily“任意地；随意地；武断地”。由句中关键词“was not selected________”与“he was chosen for the job because he had the most experience他是因为最有经验而被选做这项工作”的对应知“任意地”符合语境，故D项正确。

2.B
【句意】这一物种的雄性与雌性之间的差异会随着年龄的增长而变得更明显。
【解析】形容词词义辨析。divisible“可分的；可分割的”；pronounced“显著的；明显的”；dictated“口述的”；assured“确定的；自信的”。由句中关键词“differences差异”、“with age随着年龄的增长”的对应和词义辨析知“明显的”符合语境，故B项正确。
