Ans 18:

Actually D is correct but there is a typing mistake in D4th Tuesday of November 20XX = 28 November. The next day is 29 November. So D is correct not A. There is a typing mistake in D, but that does not mean D is wrong.

Ans 26:

Class : Class 3
The ans is A. They wrote C because no one sits on trucks. But the ans shud be A. Cuz train goes on rails, not on road. The others go on the road, not on rails. Seriously SOF! Why do u give wrong answers? it is not necessary people to sit on trucks!!!

Ans 27:

Ans 36:

Class : Class 8
You have to solve on the basis of MODE OF TRANSPORT not MEANS OF TRANSPORT SOF you yourself have given mode of transport is basis but you gave wrong answer! correct answer is A as means of transport includes transport which carry goods, passengers etc. And mode of transport means land, air or water transport. All the options are land transport but train runs on rail and other vehicles(auto rickshaw, truck and bus) run on road So answer is A

Ans 37:

Class : Class 9
Trains run on rails so Answer should be A
