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