Match List I with List II

Choose the correct answer from the options given below:

Past Participle usually ends in -ed, -en, -d, -t, used in perfect tenses or passive voice. Example: He has broken the glass. / The work was finished.

So, the selected paper was published is the past participle.

To distinguish Gerund from Present Participle: Both end in -ing, but the gerund acts as a noun (Reading is fun) while the present participle acts as a verb or adjective (She is reading / a reading lamp).
