Question

Difficulty: MediumTransitions: Cause and Effect

In forest ecosystems, mycorrhizal fungi form symbiotic networks that connect the roots of different trees, allowing them to share nutrients and chemical warning signals. When a tree is attacked by pests, it can transmit warning compounds through these subterranean pathways. _______ neighboring trees receive these signals in advance and synthesize defensive chemicals to ward off the impending threat.

Which choice completes the passage with the most logical transition?

  1. Consequently,Answer
  2. B
    Nevertheless,
  3. C
    Furthermore,
  4. D
    Subsequently,

Answer

Consequently, because it correctly indicates a cause-and-effect relationship between a tree transmitting warning compounds and neighboring trees receiving those signals to prepare their defenses.
The transition 'consequently' correctly establishes a cause-and-effect relationship between the first sentence (the transmission of warning compounds by a tree under attack) and the second sentence (neighboring trees receiving the signals and preparing defenses).

Step-by-Step Solution

1
Analyze the relationship between the sentences before and after the blank.
The first sentence describes the action of transmitting warning compounds. The second sentence describes the result of neighboring trees receiving the warning and synthesizing defenses.
Determining the logical connection is necessary to select the correct transition word.
2
Identify the type of connection between these ideas.
Since the receipt of signals and synthesis of defenses is a direct result of the compound transmission, the relationship is cause-and-effect.
This narrows down the correct transition to one that indicates a cause-and-effect relationship.
3
Evaluate the options to find the word that signals a cause-and-effect relationship.
The transition 'consequently' signals a cause-and-effect relationship, while the other choices represent contrast, addition, or chronology.
This confirms the correct choice and explains why the alternatives are incorrect.
