Question

主要在turnover这个词的理解上,还有最后一句的which的指代问题.
The single turnovers arise from the sales of the products in Germany.The turnover itself is derived from thesales of the previous period multiplied by the domestically economic development,the gross domestic product (GDP),is due to the income elasticity of demand.In addition,the turnover is influenced by the pricing of the product and weighted by the price elasticity.Alike the model considers diverse volatilities in sales,which can occur due to production,demand or external reasons.

Answer 1

【是这样】：
1、turnover 是“营业额”、“交易额”、“流通量（货币流通量）”的意思.
The single turnovers arise from the sales of the products in Germany.这句的意思是：
“单一交易额是经由各类商品在德国的各类销售所得.”,或译：“单一交易额是指在德国销售的各种单一商品的销售额.”
single 一词实际是限定：turnovers 、sales 、 products（前面加the就是这意思.）
2、which 指代 volatilities.
which can occur due to production,demand or external reasons.的意思是：
变易,可能会是由生产的、需求的或外部的诸因素而引起的（或“造成”）.
可以翻译成：
“变易可能缘于生产的、需求的或外部的诸因素.”
