Morphology
The literal parts ('live' + 'under' + 'rock') evoke physical isolation, which can metaphorically imply being cut off from news or common knowledge; the mapping from isolation to ignorance is plausible but requires metaphorical inference. A B1 learner who knows the words could probably guess the general idea (someone out of touch) but might not infer the precise sense 'unaware of current events' without prior exposure, so it is only partially transparent.
Etymology
Live under a rock comes from the image of someone actually living under a rock, hidden and cut off from news and other people. So the phrase means 'to be unaware of current events' or 'out of touch'.
