You just have to choose one of the answer types except for in question part "C" where you have to answer for both lactose and glucose levels. It either needs to be high levels, low levels, both high/low, or neither. Some of the information provided above is excess and not necessary.

Glucose levels are low; would transcription of the lac operon occur with high or low lactose levels? Both vs. none? B) For the same bacterium except it has an Is mutation instead of the I- mutation? In low glucose levels, is transcription of the lac operon taking place? C) Is the lac operon most fully transcribed in high/low lactose, as well as high/low glucose levels? (Answer must specify for the environment/levels of both lactose and glucose).
