So I am generally OK when it comes to which vs that. 'Which' is generally used to provide additional information and it doesn't affect the meaning of the sentence. 'That' is used when it is pivotal to the sentence.
For example:
1. The iPad, which connects to the iCloud, was created by Apple. (All iPads connect to the iCloud, so it’s unnecessary information.)
2. The iPad that is broken is being taken for repairs. (by using 'that' I am saying I have several iPads and the broken one is being taken for repairs. Had I used 'which', it would have meant I only have one iPad and it happens to be broken.)
Right?
OK so I may have messed up a few times in a recent article. I need help:
1. In Pakistan we have as many options to choose from between vehicles as guys have dating choices in an all-boys school, which is to say, not much.
I feel like I should have used 'that' instead of 'which'. But not sure why?
2. As a result of this monopoly we are stuck with pricey cars which have long been obsolete overseas.
I feel like I should have used 'that' instead of 'which'... because not all pricey cars in Pakistan have been long been obsolete. By using which, I am saying all pricey cars have long been obsolete. Right?
3. Another excellent alternative are the various imported Japanese cars which have flooded the market such as the Toyota Vitz and the like.
I feel I should have written 'that' again because I am talking only about the imports that have flooded the market and not the rare imports, which aren't sensible buys. Right?
4. While its spare parts are pricier than those of a Suzuki, even after crossing 100,00kms in Karachi, a well-kept Honda City will serve better than a far newer Suzuki Alto or Suzuki Cultus which start running into issues at half the distance.
OK I feel I got it completely right here. By using 'which' I am saying that all Suzuki Altos and Cultus run into issues at half the distance. Had I sad 'that', it would have meant that I am specifically talking about only the Altos and Cultus cars that run into issues, when I believe they all do.
5. Three of my friends who owned the vehicle shared various horror stories, which started when the vehicle hit close to 50,000kms
So should it be which or that here? I am so confused. I believe 'that' is the correct?
6. Perhaps the most magical option is the Sunday Car Bazaar which takes place on the outskirts of Karachi.
OK so I know I got it right here. There is only one Sunday Car Bazaar. Had I said 'that', it would have meant there were several of these Bazaars and I was talking about the one taking place on the outskirts.
7. But more importantly, a car which has been driven lovingly for 30,000 kilometers will be in far better condition that a vehicle abused for 10,000 kilometers.
Obviously I should have used 'that'.
OK. That's it.
