Question

Directions: Read the text below and answer the question that follow.

Hand sanitizers were actually invented by those who work in the medical field. In the hospital, it’s vital to keep hands free of bacteria and viruses, to avoid spreading them from patient to patient. As doctors and nurses are often rushed in their daily activities, hand sanitizers can really come in handy.

It was in the mid-IQOOS that researchers discovered alcohol (a primary germ killer) could be delivered in a gel to provide quick and easy cleansing when there’s no time or access to soap and warm water. Soap and water kill and flush germs from skin. Hand sanitizers, on the other hand, work by sitting on skin and killing germs on contact. They only work, however, if they have enough alcohol to kill the germs—at least 60 percent, according to the Centres for Disease Control and Prevention (CDC). That means a lot of alcohol on your skin (which is horrible for its health and appearance).

Once you apply the alcohol, it begins to evaporate, and it’s through this evaporation that germs are killed. If you dry off the sanitizer before it evaporates all the way, you’re actually reducing its effectiveness. However, persistent use of sanitizers —particularly early in life—can contribute to reduced immune defenses later on.

Which word in the text has the following meaning?

Continuing to exist or occur for a long period of time

This question was previously asked in
SSC Selection Post 2018 Graduation Level Question Paper (18 Jan, 2019) (Shift 3)
The correct answer is

Persistent

The correct answer is Persistent.

Continuing to exist or occur for a long time: "The persistent rain caused flooding." (Means the rain continued for a long period). Or, as in the text, "persistent use" means continuous or repeated use over time. Synonyms for persistent in the sense of duration include 'continuous', 'constant', 'ongoing', 'enduring'. However, for this question, we had to find the specific word used in the text.
