Difficulty: MediumFulfilling Specific Rhetorical and Writing Goals

When conservators at the museum began analyzing the seventeenth-century Dutch landscape painting, they noticed several patches of dark, distorted color. Over the centuries, layers of soot and yellowed varnish had accumulated on the canvas, obscuring the artist's original work. [1] The team decided to use a modern, non-invasive laser technique to clean the delicate surface.

The writer wants to add a sentence at Point [1] that introduces the specific technical challenge of removing aged debris without stripping away the historical paint itself. Which of the following choices most effectively accomplishes this goal?

  1. Traditional liquid solvents could easily penetrate the cracked varnish and dissolve the underlying oil pigments.Answer
  2. B
    Because many early pigments are highly sensitive to moisture and can easily wash away during standard cleaning procedures.
  3. C
    Chemical solvents often dissolve the varnish; while leaving the delicate layers of paint untouched.
  4. D
    Removing the grime is a delicate process, they did not want to damage the underlying paint.

Answer

Traditional liquid solvents could easily penetrate the cracked varnish and dissolve the underlying oil pigments.
The correct choice is the option discussing traditional liquid solvents penetrating cracked varnish and dissolving underlying oil pigments. This sentence is grammatically correct and successfully fulfills the rhetorical goal by identifying the specific danger that traditional cleaning methods present to the original paint layers.

Step-by-Step Solution

1
Identify the rhetorical goal requested by the prompt.
The target sentence must introduce a technical challenge of removing debris (cleaning the painting) without harming the historical paint itself.
This establishes the criteria for evaluating the choices.
2
Evaluate the choices for grammatical correctness.
The option starting with 'Because' is a fragment. The option using a semicolon creates a punctuation error by separating a dependent clause. The option with 'process, they' is a comma splice. Only the option discussing traditional liquid solvents is grammatically correct.
Eliminating grammatically incorrect options is a crucial step in ACT English.
3
Evaluate the remaining grammatically correct option against the rhetorical goal.
The option explaining that traditional liquid solvents could penetrate the varnish and dissolve the underlying oil pigments directly states the technical challenge of cleaning without damaging the paint itself.
This confirms that the grammatically correct option also fulfills the specific writing goal.
