Understanding Sentence Rearrangement

Sentence rearrangement questions test your ability to logically connect phrases or clauses to form a coherent and meaningful sentence. You need to look for grammatical cues, logical flow, and subject-verb agreement to determine the correct sequence.

Analyzing the Given Phrases

We are given four phrases:

1. A. A type of ray that could
2. B. In 1895, Wilhelm Roentgen
3. C. Penetrate objects, including human tissue
4. D. Discovered a new

Our goal is to arrange these four phrases (A, B, C, D) into a single, grammatically correct sentence that makes sense.

Evaluating the Options for Correct Sentence Order

Let's examine the structure of a typical English sentence. It often starts with a subject or a time phrase, followed by a verb, and then objects or descriptive clauses. Looking at the phrases, phrase B, "In 1895, Wilhelm Roentgen", seems like a good starting point as it provides a time and a subject.

Let's try combining phrases based on logical flow:

• Phrase B: "In 1895, Wilhelm Roentgen..." - This needs a verb indicating what he did.
• Phrase D: "...Discovered a new..." - This fits after B. So, "In 1895, Wilhelm Roentgen discovered a new..." - Discovered what?
• Phrase A: "...A type of ray that could..." - This fits after D. So, "In 1895, Wilhelm Roentgen discovered a new type of ray that could..." - What could this ray do?
• Phrase C: "...Penetrate objects, including human tissue." - This describes what the ray could do and fits after A.

Combining B, D, A, and C in this order gives us the sentence: "In 1895, Wilhelm Roentgen discovered a new type of ray that could penetrate objects, including human tissue."

This sentence is grammatically correct and historically accurate, referring to the discovery of X-rays.

Comparing with the Given Options

Now let's check if the order B, D, A, C matches any of the provided options:

• Option 1: C, A, D, B
• Option 2: D, B, C, A
• Option 3: A, C, B, D
• Option 4: B, D, A, C

Our derived order B, D, A, C matches Option 4.

Step-by-Step Rearrangement Process

1. Identify potential starting phrases. Phrase B ("In 1895, Wilhelm Roentgen") is a strong candidate as it introduces the subject and time.
2. Look for a phrase that logically follows the subject and time. Phrase D ("Discovered a new") describes the action taken by Wilhelm Roentgen. So, B followed by D.
3. Determine what was discovered. Phrase A ("A type of ray that could") specifies what was discovered. So, B followed by D followed by A.
4. Identify the action or property of the discovery. Phrase C ("Penetrate objects, including human tissue") describes what the ray could do. So, B followed by D followed by A followed by C.
5. Verify the complete sentence: "In 1895, Wilhelm Roentgen discovered a new type of ray that could penetrate objects, including human tissue."
6. Confirm that this sequence (B, D, A, C) is present in the options.

Thus, the correct arrangement of the phrases is B, D, A, C.

Additional Information: Wilhelm Roentgen and X-rays

The sentence formed refers to a significant scientific discovery. Wilhelm Roentgen was a German physicist. In 1895, while working with cathode rays, he discovered electromagnetic radiation that could pass through solid objects. He called these unknown rays "X-rays". His discovery revolutionized medicine by allowing doctors to see inside the human body without surgery. For this groundbreaking work, Roentgen was awarded the first Nobel Prize in Physics in 1901.

Understanding the context of the phrases can sometimes help in rearranging them, especially in questions related to historical or scientific facts.
