Identifying these structural elements allows the reader to break down a dense, 33-word sentence into distinct logical units, rather than processing it as a cognitively overwhelming string of words. Recognizing the subordinating conjunction “Although” immediately signals a contrast between technological advancement and the continued reliance on fossil fuels. Identifying the causal subordinating conjunction “because” clarifies the economic obstacles underlying this reality.
Furthermore, isolating complex noun phrases such as “immense capital investment” clarifies the specific requirements being discussed, while the relative pronoun “which” directly links the subsequent point to funding difficulties in developing regions. By mapping these syntactic markers, the reader can trace how technological progress, financial constraints, and geopolitical equity interact within a single, coherent argument.
