He or she can decide within a very limited amount of time, under great pressure, potentially, depending on the scenario, maybe based on a miscalculation or a misunderstanding, they can decide the fate of millions of lives: yours, mine, our community’s.
*I don’t believe the following example qualifies for this grammar because the ‘of phrase’ is not that which is referred to:
We have developed a comprehensive COVID-19 relief and recovery response for our community, that was surfaced from our community, focused on five primary areas of need, and already servicing families like Sean’s.
This is not a clearly explained point from the English Grammar Profile. When we turn to the first example they give:
Our_APPGE after-sales_JJ team_NN1 now_RT is_VBZ perceived_VVN as_CSA faster_JJR ,_, more_RGR qualified_JJ ,_, friendlier_JJR and_CC more_RGR efficient_JJ than_CSN our_APPGE competitors_NN2 ‘_GE ._.
there is no ‘of’ in it. Maybe they are saying that ‘of’ can be elipted as in ‘that of our competitors’. The next examples they give is easier to understand:
your_APPGE hour_NNT1 of_IO peacefulness_NN1 might_VM considerably_RR differ_VVI from_II your_APPGE neighbours_NN2 ‘_GE ._.
a_AT1 student_NN1 ‘s_GE view_NN1 of_IO the_AT college_NN1 ,_, not_XX only_RR a_AT1
teacher_NN1 ‘s_GE ._.
In conclusion, this grammar point is very hard to locate. We can try searching in iWeb for:
_N of _N _GE .
but it produces nothing but quite a useless set of data:
1 GAME OF THRONES ‘ . 122
2 RISK OF ALZHEIMER ‘S . 115
