   Artifacts from early in the Upper Paleolithic period are harder to identify than those that originated

   There are more lamps known from the late period, because ... it's harder to classify and identify artifacts from the early period. This is a causal explanation for why the stuff we find from the late period can be more feasibly classified as lamps. We find stuff from the early period, but is it a lamp? Hmm, not sure. Let's put it in the "unknown" pile.

   More archaeological sites have been discovered from the Magdalenian culture than

   There are more lamps known from the late period, because ... that was the time period when Magdalenian culture was dominant and we have more artifacts from Magdalenian (including lamps) than we do from earlier cultures. This is a causal explanation for why we would find more lamps from the late period.

   More efficient lamp-making techniques were developed by the Magdalenian culture than

   There are more lamps known from the late period, because ... that was the time period when Magdalenian culture was dominant and Magdalenians made lamps more efficiently than earlier cultures (so it would have been feasible for them to make more lamps). This is a causal explanation for why there may have actually been more lamps in the late period.

   Fire pits were much more common in caves early in the Upper Paleolithic period than they were

   There are more lamps known from the late period, because ... in the early period, they used fire pits more commonly to illuminate their caves. This is a causal explanation for why we there may have been fewer lamps in the early period (they were less popular than fire pits).

   More kinds of lamps were produced by the Magdalenian culture than

   Why this is right

   This feels tempting since Magdalenian was dominant during the late period, so this is saying "there were more kinds of lamps produced during the late period than during the early period". But does producing more types of something make it more likely that we'd find a greater number of them? To explain why we find a greater quantity of lamps in the late period, we need to know there were more lamps in the late period, or if there were a comparable number of lamps why it's easier to find more lamps from the late period. But having different kinds of lamps doesn't have any common sense connection to overall quantity of lamps that would have been left as artifacts. A car dealership that sells "more kinds of cars" than another car dealership doesn't necessarily have more cars on the lot. They have a wider variety, but that doesn't mean they have a larger quantity.
