I have come across the following sentence : 'There is a general rise in prices such as occurred in the late 60's'. I would like to know whether the word 'as' is functioned as a conjunction or relative pronoun.
Is the word 'such' an adjective modifying the word 'prices'? if so, can i put 'such' in front of 'prices'?
One more example: 'As can be imagined, estimating the value of properties on a regular basis can be a large task' Is the word 'as' a relative pronoun or conjunction?
