29. It can be learned from Paragraphs 5 and 6 that open access terms _____

【答案】[A] allow publishers some room to make money.

【解析】由第五段最后一句“... paywalled for a year or more so that the publishers can make a profit before being placed on general release”可知，公开授权条款的出版物有可能设置一年或更久的时间限制，为出版商获利留出了一定的余地，因此A 选项正确。B、C 选项并未出现，D 选项在第六段被反驳，因为第六段明确提出“Yet the new system has not worked out any cheaper for the universities.”，故选 A。
