Question

Difficulty: MediumTransitions: Addition and Similarity

The following passage discusses mechanisms of avian navigation. Complete the text by writing the transition word or phrase that most logically establishes a relationship of similarity between the two findings.

Answer:In studies of avian navigation, researchers have discovered that migratory songbirds possess iron-rich cells in their beaks that function as a magnetic compass. 【Similarly】, homing pigeons utilize magnetic field receptors located within their inner ears to navigate across unfamiliar terrains.

Answer

Similarly (or Likewise)
The correct transition logically connects the parallel observations in both sentences. The first sentence notes that migratory songbirds use beak-based magnetic receptors for navigation, and the second sentence notes that homing pigeons use ear-based magnetic receptors. The transition words 'Similarly' or 'Likewise' accurately establish this relationship of similarity.

Step-by-Step Solution

1
Analyze the relation between the two sentences.
The first sentence describes how migratory songbirds navigate using magnetic receptors in their beaks. The second sentence describes how homing pigeons navigate using magnetic receptors in their inner ears.
To choose the correct transition, we must understand how the information in the second sentence relates to the information in the first.
2
Identify the type of connection.
Both sentences describe different bird species using magnetic sensory systems to navigate. This is an analogy or a similarity between two distinct scientific observations.
Since the two sentences describe parallel phenomena, the transition must signal addition or similarity.
3
Select the correct transition word.
Words like 'Similarly' or 'Likewise' fit the sentence-initial position and properly connect the parallel observations.
These transitions establish a clear connection of similarity without introducing incorrect contrast, sequence, or causality.
