question:
In the morning of 19 April 2016, Taliban militants attacked a security team. Or On the morning of 19 April 2016, Taliban militants attacked a security team .
answer:
'on' is the correct preposition and 'in' is the incorrect one for this case. 'The morning of' functions as an adjectival phrase clarifying the specific time and date 'on 19 April 2016'. 'On' is used because it belongs to the date here, specific part of the day. The normal language constructions would be: on + date (with the year or without it) or day of the week in + morning, afternoon, evening (in the morning, in the evening) But, when we talk about a specific morning, afternoon, or when we describe the part of the day it should be used with on: on the morning of [date], You can't say 'I will see you on the morning' - it's incorrect. In or on? We use in with morning, afternoon, evening and night, but we use on when we talk about a specific morning, afternoon, etc., or when we describe the part of the day.

question:
There was the following passage in New York Times' (October 6) article commenting on GOP Presidential candidate, Carly Fiorina under the headline, 'If she's a feminist, then I'm a T. Rex': 'Her record at Hewlett-Packard firing skilled Americans by the thousands and outsourcing their jobs to China and India, while almost running her company into the ground with an ill-advised merger is hardly a sterling record for any sort of candidate, assuming we actually want a president of all the people rather than a modern Ebenezer Scrooge, - - This is a woman who would deny other women control over their own bodies, as well. 'If she's a feminist then I'm a T. rex.' According to Jurassic wiki, Tyrannosaurus rex, the most famous of all dinosaurs species and commonly known as T. rex, was the largest of the Tyrannosaur family and by extension one of the largest theropods, reaching 12 to 13 meters in length. But what does 'If she's a feminist, then I'm a T. Rex' mean? Does the writer sarcastically admit herself being anachronistic? Why should it be a T.Rex, not other monsterous or supernatural creatures, say, Moby-Dick and Godzilla? Is this a cute turn of phrase? Could you translate 'I'm a T.rex' into plain English?.
answer:

All that that is saying is that she is no feminist whatsoever, being just as much of a feminist as the columnist is a giant extinct dinosaur. That is, not at all.
