If I am writing a sentence using simple past and past perfect, and in the next sentence I want to emphasize that there was another action completed even more earlier, which tense shoud I use in the second sentence?
On 1 September, the company announced that it had started its works [it started works before announcing it]. The company revealed/had revealed the project plans three months ago. [at first it reavealed plans, and then it started works]
Should I use revealed or had revealed?
