1) In 1905 Einstein interpreted the “photoelectric effect” of light, a phenomenon that cannot be explained by the wave theory of light. (2) When a photon strikes an electron, the resulting action is analogous to the collision of billiard balls. (3) The effect of such collisions can be observed when light falling on a metal plate produces a shower of electrons. (4) Einstein deduced that light is not a continuous stream of energy but is composed of individual particles or bundles of energy, which he called photons.

4) Although sentence 1 is placed appropriately, the rest of the paragraph above is not well organized. Which of the following reorderings of sentences 2-4 most improves the continuity of the paragraph?
A) 2, 4, 3
B) 3, 2, 4
C) 3, 4, 2
D) 4, 2, 3
What do YOU think is the best order?
To determine the best reordering, we need to consider the logical flow of ideas and ensure that the sentences are connected smoothly.
Sentence 1 serves as the initial statement that sets the context for the paragraph. Sentence 2, which discusses the photoelectric effect, directly relates to Einstein's interpretation mentioned in sentence 1.
Sentence 3 provides an example or evidence to support sentence 2, as it describes the observable effect when light falls on a metal plate.
Lastly, sentence 4 concludes the paragraph by stating Einstein's deduction based on the explained phenomenon.
Considering this logical flow, the best reordering of sentences 2-4 would be:
C) 3, 4, 2
Sentence 3 presents the observable effect, which creates a smooth transition to sentence 4, where Einstein's deduction is mentioned. Then, sentence 2, which discusses the photoelectric effect, logically follows as it builds upon Einstein's deduction.
Therefore, the correct answer is C) 3, 4, 2.
