I disagree with all of your answers. BTW, I've seen these questions before, otherwise I'd have no idea from this post what dialogue you're referring to.

To identify which sentence is using the appositive phrase correctly, you need to understand what an appositive phrase is. An appositive phrase is a noun or noun phrase that renames or provides additional information about another noun or pronoun in a sentence.

In this case, an appositive phrase is used to provide additional information about the Grand Canal in China.

Now let's examine the sentences:

a. The Grand Canal, which is the oldest man-made waterway in the world, is still used today in China.

This sentence correctly uses an appositive phrase by providing additional information about the Grand Canal without disrupting the sentence's meaning or structure. Therefore, sentence a is using the appositive phrase correctly.

b. The Grand Canal in China is a man-made waterway, still used, that is the oldest in the world.

In this sentence, the appositive phrase "still used" is not placed correctly. An appositive phrase should be adjacent to the noun it is modifying. Therefore, sentence b is not using the appositive phrase correctly.

c. The Grand Canal in China, the oldest man-made waterway in the world, is still used today.

This sentence correctly uses an appositive phrase by providing additional information about the Grand Canal without disrupting the sentence's meaning or structure. Therefore, sentence c is using the appositive phrase correctly.

d. The Grand Canal – which is an old, man-made waterway in China – is still used today.

In this sentence, the appositive phrase "which is an old, man-made waterway in China" is enclosed in dashes rather than being placed adjacent to the noun it is modifying. An appositive phrase should be directly next to the noun it renames. Therefore, sentence d is not using the appositive phrase correctly.

Therefore, the correct answer is: sentence a is using the appositive phrase correctly.

For the second question:

To determine which directions indicate the different elements of a play, you need to understand the different components of a play.

I. The tone of voice an actor should use indicates the emotional quality or attitude a character portrays through their voice.
II. An action an actor should take indicates a physical movement or gesture performed by a character.
III. The scenery refers to the visual elements on stage, such as the set, props, and background.
IV. Sound effect indicates any auditory element, such as music, noises, or voices, used to enhance the play's atmosphere.

Option a states that only I and II indicate the different elements, which is incorrect as it does not include scenery or sound effect.

Option b states that I, II, and IV indicate the different elements, which is correct as it includes all the components.

Option c only includes III and IV, which is incorrect as it does not include the actor's tone of voice or actions.

Option d claims that all elements, I through IV, indicate the different components, which is incorrect as it excludes options III.

Therefore, the correct answer is: option b, which states that I, II, and IV indicate the different elements.

For the third question:

To identify the humorous technique used in the dialogue, you need to analyze the dialogue for the presence of specific humorous elements.

Option a states that the situation is completely illogical. This option does not provide enough information about the humorous technique used in the dialogue.

Option b claims that the conversation is exaggerated in every way. This option suggests that the dialogue involves exaggerated elements, but it does not specify which specific technique is being used.

Option c states that physical humor is indicated in the stage directions. This option suggests that the dialogue involves physical humor, which is a specific humorous technique.

Option d claims that there is a contrast between the truth and a mistaken view. This option does not provide enough information about the humorous technique used in the dialogue.

Therefore, the correct answer is: option c, which states that physical humor is indicated in the stage directions.
