Read the following poem and answer the questions that follows:
Are You There?
My father and I shove back the furniture
to the four walls of the sitting room
then lie on the carpet wearing blindfolds,
his left hand holding my left hand
Are you there, Moriarty? he enquires, before tightening (I imagine) the grip on his rolled-up copy of yesterday’s Times. There is only one possible answer to that.
I give it while rolling away to the side but still clasping his hand, still in range, and sure enough he manages a direct hit. Now it is my turn, but the moment I lift my weapon I realise there is no reason to continue I can tell from his stillness, and the chill and stiffness of his fingers, he has been dead for a good while already.

The ‘weapon’ mentioned in the first line of the fourth stanza of the poem is

The correct option is A Rolled-Up Newspaper.

Step-by-step Explanation:
1. Identify the Context: The poem describes the speaker and their father playing a traditional game (commonly known as "Are You There, Moriarty?"). In this game, two blindfolded participants lie on the floor, hold hands, and take turns attempting to hit each other with a rolled-up paper.
2. Examine the Clues in the Poem: In the second stanza, the father prepares to strike, "tightening (I imagine) the grip on his rolled-up copy of yesterday’s Times." Since The Times is a prominent newspaper, the father is using a rolled-up newspaper as his striking instrument.
3. Determine the Speaker's "Weapon": In the fourth stanza, the speaker says, "Now it is my turn, but the moment I lift my weapon I realise there is no reason to continue". Since both players use the same equipment in this game, the speaker's "weapon" refers to the same object—a rolled-up newspaper.
Therefore, the "weapon" mentioned in the first line of the fourth stanza is a rolled-up newspaper.
