Correct option is A
Option a, "contributes," is the most appropriate choice to fill in the blank. Here's why:
·
Contributes (a): This word means to help to cause or bring about. In the context of the sentence, it suggests that working in dim light can help lead to or increase the risk of eye issues such as glaucoma. This is a common notion that reducing eye strain by providing adequate lighting is beneficial for eye health.
·
Precipitates (b): Although "precipitates" could technically fit, as it means to cause something to happen suddenly or sooner than expected, it usually has a more immediate, often negative connotation. It's not the most typical word used in health contexts like this unless the result is quite direct and rapid.
·
Eradicates (c): This word means to completely remove or get rid of something. It's incorrect in this context as working in dim light does not eradicate or eliminate eye issues.
·
Eliminates (d): Similar to "eradicates," "eliminates" means to completely remove or get rid of something. It would not make sense to use it here as working in dim light does not lead to the elimination of eye issues but rather could contribute to them.
Thus, "contributes" (a) is the best fit, reflecting the additive effect of working in dim light on the development of eye conditions like glaucoma.
