Knowledge of Language

Although early computer scientists predicted that machine translation would be a straightforward task, the nuances of human language proved incredibly complex. Modern translation software must parse idiomatic expressions that do not translate directly, which is a problem that poses a challenge because it is difficult for algorithms to resolve without contextual clues. Consequently, developers must integrate semantic analysis to help the software comprehend the underlying intent of the speaker.

However, these vents, emitting mineral-rich water at temperatures exceeding 600��F, supported complex communities of giant tube worms, blind crabs, and ghost-like fish. These organisms thrived in complete darkness, obtaining sustenance not from photosynthesis but from chemosynthetic bacteria, which are bacteria that generate energy by oxidation of chemical compounds, a process that produces energy from chemicals instead of from the sun.

Which of the following choices, when replacing the underlined portion of the sentence, is the most concise and grammatically correct?

As the restoration of the fourteenth-century fresco began, the conservators faced a daunting task: the original pigments had degraded so severely that the figures were barely visible.
