Radioactive.

Explanation:

A geologic column can be defined as a collection of rock layers that are typically grouped based on their relative ages in a descending order i.e from oldest to the youngest.

Generally, the layers of the rock that are found in various parts of the world are known to be different because they all comprises of distinct Earth's geological history.

In Science, absolute dating can be defined as a process used to accurately determine the age of a rock or fossil by measuring the decay of isotopes associated with the rock or within the fossils.

Generally, absolute dating relies on radioactive elements such as uranium, polonium, thorium, francium, radon, etc., which are mainly unstable elements that release energy as they break down through fission.

In conclusion, these informations when properly obtained can be used to determine the age of any historical monument or material such as earth, rocks, animals, plants, etc., because the parent material decays into a stable daughter elements at a constant decay rate.

I would say that the sentence that best analyses the poets use of allusion in this passage from The Lovesong of J. Alfred Prufrock is A: The speakers refers to Michelangelo to show how people pretend to be who they're not so they can fit in.

Explanation:

An allusion in literature occurs when the writer makes a reference to a person,  place, thing or idea of historical, cultural, literary or political significance to try to explain better what he/she wants to express. In this case, the writer refers to Michelangelo in order to describe people who pretend to be -or to know- about cultural stuff. These people try to show themselves as experts in art by talking about Michelangelo just to fit in.
