Hi Aravind,
Both of those sentences would be considered full clauses. The first sentence has a complete verb, with an auxiliary + "been" + "-ing" construction [i.e., the passive form of either the present or past perfect continuous tenses]. Generally, whenever we have an auxiliary (is/was/are/has been/am etc.) present before an "-ing" word, the "-ing" will act as a full independent verb.
In the second sentence also, "worked" is a verb, since it describes the "
Action" performed by the subject. The tricky thing with "-ed" phrases, when they don't have a preceding auxiliary verb, is that they can
act as either Verbs or Adjectives. In such cases, you want to test whether the "-ed" phrase is simply describing a noun (in which case it will be an adjective), or whether it is describing an Action performed (in which case it will be a verb).
For example:
John located the store ---> "Located" here is a verb because it
describes the action performed by John
But,
The store located in India was built in 1900. ----> "Located" here is an adjective because it describes the store.
Hope this helps - please let me know if you need further help or anything is unclear.
Happy prepping!
