Answer:
Trilobites
Explanation:
The Phanerozoic Eon is characterized by the presence of organisms that possessed hard shells as an adaptation to the environmental conditions. Among these organisms, the most common hard-shelled animals were the trilobites.
Trilobites were present during most of the Paleozoic Era, which belongs to the Phanerozoic Eon. These animals were marine organisms with remarkable and unique phenotypes.
The body of a trilobite was composed of three segments: the cephalon, the thorax, and the pygidium (tail). In addition, they possessed an exoskeleton composed of chitin, which was the reason behind their hard shells. They shed their exoskeletons to be able to grow.
Trilobites are currently extinct.

To understand this answer, one must understand the mechanism of correction of inflationary processes.
Inflation erodes the purchasing power, thus, the elderly with fixed income will be harmed and not beneficiaries in an inflationary process.
<u>The main mechanism to reduce inflation is the interest rate.</u> In this way, when inflation happens, the Federal Reserve raises the interest rate. This makes public bonds profitable and economic agents begin to use money by buying bonds, reducing the circulation of money and consequently lowering inflation.
For banks that have made adjustable rate loans, this will be a good thing, as interest on the contracts will increase along with the increase in the interest rate, which will make the contracts yield more. Therefore, banks will be the biggest beneficiaries. However, this will happen only when the rate is adjustable.
