参考解析
解析：本题考察定语从句。题目意为“最早的电话需要一对不同的线路分别给本机和想要接通的电话。”本题是介词+关系代词形式，connect表示连接二者时，需要介词，connect sb/sth with/to sth。关系代词which在定语从句中作介词的宾语时,可以跟介词一起放在主句和从句之间，这时的关系代词不能省略;有时为了使关系代词紧跟它所修饰的先行词,也可以把介词放在从句中有关动词的后面,这时的which可用that替换。

考题
Glove Co makes high quality, hand-made gloves which it sells for an average of $180 per pair. The standard cost of labour for each pair is $42 and the standard labour time for each pair is three hours. In the last quarter, Glove Co had budgeted production of 12,000 pairs, although actual production was 12,600 pairs in order to meet demand.37,000 hours were used to complete the work and there was no idle time. The total labour cost for the quarter was $531,930.At the beginning of the last quarter, the design of the gloves was changed slightly. The new design required workers to sew the company’s logo on to the back of every glove made and the estimated time to do this was 15 minutes for each pair. However, no-one told the accountant responsible for updating standard costs that the standard time per pair of gloves needed to be changed. Similarly, although all workers were given a 2% pay rise at the beginning of the last quarter, the accountant was not told about this either. Consequently, the standard was not updated to reflect these changes.When overtime is required, workers are paid 25% more than their usual hourly rate.Required:(a) Calculate the total labour rate and total labour efficiency variances for the last quarter. (2 marks)(b) Analyse the above total variances into component parts for planning and operational variances in as much detail as the information allows. (6 marks)(c) Assess the performance of the production manager for the last quarter. (7 marks)
