Question:
What investigation ?
We need the paragraph in order to help
The correct way of matching each statement with the appropriate tone is the following:
* Angry tone: the adjective “annoying” implies the angry tone of the speaker. (A cell phone can be annoying when you forget to turn on the silent feature before going to sleep)
* Accepting tone: the speaker acknowledges the problem with the battery, yet she/he accepts it by carrying a charger as a solution to it. (The problem is that the battery doesn’t last long, but I don’t mind carrying a charger)
* Objective tone: the speaker is objective by stating only facts about the device. (The cell phone makes calling convenient from all possible locations)
* Sentimental tone: the verb “cherish”, and the noun “gift” imply the sentimental tone of the speaker. (I will always cherish my first cell phone because it was a gift from my dad)
* Optimistic tone: the speaker has an optimistic tone, as she/he speaks about a possible future development. (I think we can soon expect a technology that charges phones in seconds)
