Doctor Strange was visited by a family. Some of them were having problems hearing some sounds. The doctor decided to test each family members' hearing by measuring the highest frequency sound they could hear. The loudness of each sound was kept the same. The results are shown in this table. Name Age Highest frequency that can be heard (Hz) Gabriella 74 9000 Carlos 50 16500 Safia 44 18000 Lily 24 8000 Ahmed 17 20000 Imagine you are Doctor Strange. Who would you recommend have further tests to check whether they might have a disease or other problem affecting their hearing?

In the given table the name Lily with the age 24 will be recommended for further tests to check whether she might have a disease or other problem affecting her hearing. Note: As we age, it’s the upper frequencies we lose first. So by the time we hit middle-age, we can expect to hear up to around 14 , 000 Hz . Age-related hearing loss (or presbycusis) naturally develops as we age and our hearing can begin to deteriorate as a result of external factors, including the environment and existing medical conditions.

Doctor Strange was visited by a family. Some of them were having problems hearing some sounds.
The doctor decided to test each family members' hearing by measuring the highest frequency sound they could hear. The loudness of each sound was kept the same. The results are shown in this table.

Name	Age	Highest frequency that can be heard (Hz)
Gabriella	$74$	$9000$
Carlos	$50$	$16500$
Safia	$44$	$18000$
Lily	$24$	$8000$
Ahmed	$17$	$20000$

Describe any pattern you can see in the results
