After epilation, absence of any skin reaction may indicate which statement is true?

• A. The current was so mild that only the weakest hairs could be permanently removed.
• B. No hairs were treated.
• C. A skin reaction always occurs with successful treatment.
• D. The current was too high and caused skin damage.

Answer: (A)

The situation tests how the strength of the current during epilation relates to the skin’s reaction and which hairs get permanently destroyed. When the current is very mild, the skin’s response tends to be minimal or absent, yet some hairs—specifically the ones with the weakest follicles—can still be permanently removed. That’s why absence of any skin reaction can indicate that the current was so mild that only the weakest hairs were permanently removed.

If no hairs were treated, you’d also expect little or no skin reaction, but the stem implies that some epilation occurred. A skin reaction does not always accompany successful treatment, so claiming that a reaction always occurs is not accurate. If the current were too high, skin damage would be likely, which would typically produce a visible reaction, not an absence of one.
