Hello,

According to http://grammar.ccc.commnet.edu/grammar/phrases.htm#infinitive, "to keep one's job", as an infinite phrase, can also function as a noun subject of this test sentence of Question 10. For this reason, the test answer should also include this "to keep", shouldn't it? Could you please double-check this addition "to keep"?

You are correct Bhikku.
'to keep one's job' and 'keeping one's job' are both acceptable there. However the computer answer key cannot distinguish this.
