Answer 2

The completed meaningful sentence is as follows:

In the past twenty decades, no new antibiotic has been discovered to manage rabonella infection among adults.

Using has been:

• "Has been" is used in the third-person singular, while "has been" is used in the first- and second-person singular, as well as all plurals.
• The present perfect tense refers to an action that began in the past and is still ongoing.
• If the sentence's subject is He-She-It or a single word (vehicle, bird, child), we use 'has been.'
• Examples
• My car has been stolen from the city center.
• This bird has been following me around all day.
• "Have been" is used in the present continuous perfect tense in the first, second, and third person plural forms, but "has been" is only used in the third person singular form.
