elaborate用得好。
elab·o·rate /ɪˈlæbərət/ adjective
[more elaborate; most elaborate] : made or done with great care or with much detail : having many parts that are carefully arranged or planned
▪ They made elaborate preparations for his visit.▪ I see now that her behavior was all part of an elaborate plan/plot/scheme.▪ The dancers were wearing elaborate costumes.▪ He told the story in elaborate detail.▪ an elaborate meal
the last night's difficulty - 觉得这里无须用the? 这好象 the his book 里的 the 是多余的？
这一句：however, the last night’s difficulty in carrying it out caused further tension that a key dialog is under way.
简化了后：
difficulty（主语） caused （谓语）tension（宾语）.
假如加上"that a key dialog is under way"，that从句在句子里做什么成分？
