Answer:
you should use possessive pronouns or add an apostrophe and the letter s (that is, 's) to the noun to indicate ownership.
Step-by-step explanation:
When there is a noun followed by a gerund, possession is expressed by adding to the noun. A few examples of a noun + gerund with a possessive case are:
~The policeman got immediately into the burglar's house.
Besides, possessive pronouns are also used to indicate ownership before gerunds, as in:
~His loud talking disturbed the patients at the hospital.
~Their expensive travelling made people jealous.
