Explanation:

What is gap-filling?

Gap-filling is to fill up the gaps with suitable words so that the sentence becomes meaningful and complete.

• Here the given blanks are filled with Present Perfect Tense.
• Present perfect tense denotes an action which has just finished.
• The structure of present perfect tense is - Has/Have + V3 form of verb.
• "Has" is used with singular nouns and pronouns.
• "Have" is used with "I" and plural nouns and pronouns.
• In present perfect tense always V3 form of verb is used.
• V3 form of verb is the past participle form of verb.
• As the nouns before both the given blanks are singular, both will take singular verb "has".
• The V3 form of the verb "be" is "been".
• The V3 form of the verb "increase" is "increased".
• Thus the 1st blank will be filled with "has been".
• While the 2nd blank will be filled with "has increased".

Thus after filling the gaps the passage will be-

Urbanization has always been a problem which causes several environmental challenges ever since the rate of migration has increased after the industrial revolution.
