Question

which of the following is a reasonable conclusion based on the data? ultraviolet light is a viable strategy to reduce viral count. the length of ultraviolet light exposure affects viral count. the longer the virus is exposed to ultraviolet light, the greater the viral count. the length of ultraviolet light exposure has no effect on the viral count. the longer the virus is exposed to ultraviolet light, the greater the reduction in viral count.

Explanation:

To determine the reasonable conclusion, we analyze each option:

• Option 1: Just states UV is viable but doesn't relate to data (likely about exposure length).
• Option 2: "Affects" is vague; we need a more specific trend.
• Option 3: UV light typically reduces viruses, so longer exposure increasing viral count is illogical.
• Option 4: Contradicts the known effect of UV on viruses (it should have an effect).
• Option 5: UV light is germicidal; longer exposure would lead to more virus reduction (e.g., more time for UV to inactivate viruses), so this follows the expected relationship between exposure length and viral count reduction.

Answer:

E. The longer the virus is exposed to ultraviolet light, the greater the reduction in viral count.
