Problem 7 - Entrance Test

A recent study highlighted the increasing prevalence of remote work. [1] This shift has profound implications for urban planning and transportation. [2] Many companies report increased employee satisfaction and productivity. [3] However, challenges such as maintaining team cohesion and ensuring data security remain. [4] The writer wants to add the following sentence: 'This trend is largely driven by advancements in digital communication technologies.' Where would the sentence best be placed?

Correct: A

The added sentence explains *why* the prevalence of remote work is increasing. It provides a direct cause for the trend mentioned in the first sentence. Placing it after sentence [1] (which states the increasing prevalence) and before sentence [2] (which discusses its implications) provides immediate and logical context for the phenomenon.
