A well-controlled experiment was conducted where researchers noted that a new antibiotic eliminated a bacterial sinus infection. Which of the following can be inferred from this result?

The most likely explanation for the elimination of the sinus infection is that the medicine killed the bacteria. Antibiotics are drugs that kill or halt the growth of bacteria, so this is the most likely explanation for the elimination of the sinus infection since the antibiotics do not have an influence on a person’s allergies or DNA.
