- D) Three officials had been suspended by the authorities pending a thorough investigation into the matter.
Answer: C) Three officials have been suspended by the authorities pending a thorough investigation into the matter. (The active voice present perfect tense "have suspended" is changed to the passive voice present perfect tense "have been suspended" — the object "three officials" becomes the subject — the subject "the authorities" becomes the agent introduced by "by" — the auxiliary structure changes from "have + past participle" to "have been + past participle.")

Answer: C) A magnificent new cultural centre for the city is being designed by the renowned architect.

Answer: D) Several important reforms had already been implemented before the elections by the government. (The active voice past perfect tense "had implemented" is changed to the passive voice past perfect tense "had been implemented" — the object "several important reforms" becomes the subject — the adverb "already" is retained in its position — the auxiliary structure changes from "had + past participle" to "had been + past participle.")

Answer: A) A series of groundbreaking experiments was being conducted at the research laboratory by the scientists. (The active voice past continuous tense "were conducting" is changed to the passive voice past continuous tense "was being conducted" — "a series of groundbreaking experiments" becomes the subject and takes the singular verb "was" as "a series" is singular — the auxiliary structure changes from "were + verb-ing" to "was being + past participle.")

- D) The priceless antique vase is being stolen from the museum overnight.
Answer: A) The priceless antique vase has been stolen from the museum overnight. (The active voice present perfect tense "has stolen" is changed to the passive voice present perfect tense "has been stolen" — since the subject is the indefinite pronoun "someone" indicating an unknown agent it is omitted in the passive voice — the object "the priceless antique vase" becomes the subject.)

- D) All the senior teachers were called to an emergency meeting this morning by the principal.
Answer: D) All the senior teachers were called to an emergency meeting this morning by the principal. (The active voice simple past tense "called" is changed to the passive voice simple past tense "were called" — the object "all the senior teachers" becomes the subject — the auxiliary "were" is added before the past participle "called" — the time expression "this morning" is retained in its position.)

Answer: A) Free medical assistance has been provided to the underprivileged families for years by the organisation. (The active voice present perfect continuous tense "has been providing" is changed to the passive voice present perfect tense "has been provided" — in English the present perfect continuous passive "has been being provided" is grammatically possible but rarely used in practice — "has been provided" is the preferred and more natural passive form.)

(The active voice sentence with the modal verb "should" is changed to the passive voice by placing the modal "should" before "be" followed by the past participle — the subject "they" is omitted as it is indefinite — the object "all the pending work" becomes the subject — the auxiliary structure changes from "should + base verb" to "should be + past participle.")
