某工厂有女职工130人，比男职工人数的3倍还多4人，有男职工多少人？

国内油价与国际油价相比一向是“涨快跌慢”，原因之一是我国成品油调价依据的是原油价格变动超过4%这个边界条件。比如，从100美元一桶涨到104美元时，我们就跟着涨价；但是，从104美元同调4%再降价，则要等价回落到99.84美元。两个条件实际上是不同的，降价要求的条件更高，更不容易达到。
以下哪些陈述最好地指出了上述论证的缺陷

A．上述论证没能说明，国内油价不合理是由多种原因造成的。

B．上述论证没能说明，国内油价不合理的根本原因在于行业垄断。

C．上述论证没能说明，以4%为边界条件，则油价越高，国内反应越快。

D．上述论证没有从相同的价格基点出发进行比较，如果涨价的基点是100美元，对降价的条件分析也应该以100美元为基点。

Information systems design is defined as those tasks that focus on the specification of a detailed computer-based solution. Typically, there are four systems design tasks for in-house development.

①The first task is to specify （1）, which defines the technologies to be used by one, more, or all information systems in terms of their data, processes, interfaces, and network components. This task is accomplished by analyzing the data models and process models that are initially created during requirements analysis.

②The next systems design task is to develop the （2）. The purpose of this task is to prepare technical design specifications for a database that will be adaptable to future requirements and expansion.

③Once the database prototype has been built, the systems designer can work closely with system users to develop input, output and dialogue specifications. The （3）ust be specified to ensure that the outputs are not lost, misrouted, misused, or incomplete.

④The fourth design task involves packaging all the specifications from the previous design tasks into a set of specifications that will guide the （4） activities during the following phases of the systems development methodology.

Finally, we should （5） and update the project plan accordingly. The key deliverable should include a detailed plan for the construction phase that should follow.

（5）是（）
