Difficulty: MediumSentence-Level Transitions

The following passage is an excerpt about a unique desert plant.

Most desert plants survive by extending deep taproots to access water hidden far underground. The Welwitschia mirabilis, a unique gymnosperm native to the Namib Desert, takes a different approach. It relies on morning fog that rolls in from the Atlantic Ocean, absorbing water directly through its two broad, weather-beaten leaves. [1] Additionally, its root system remains remarkably shallow, serving primarily to anchor the plant rather than to seek deep water sources.

Which choice best completes the underlined portion [1]?

  1. A
    NO CHANGE
  2. B
    However,
  3. Consequently,Answer
  4. D
    DELETE the underlined portion.

Answer

The transition 'Consequently,' is the correct choice because it accurately establishes the cause-and-effect relationship between the plant's leaf-based water absorption and its shallow root system.
The transition 'Consequently,' is correct because it accurately establishes a cause-and-effect relationship: because the Welwitschia mirabilis absorbs water directly through its leaves from fog, it does not need deep roots to search for underground water, making the shallow root system a direct result of its water-absorption method.

Step-by-Step Solution

1
Analyze the relationship between the preceding sentence and the sentence containing the transition.
The preceding sentence explains that the Welwitschia mirabilis absorbs water from fog through its leaves. The next sentence notes that its root system is shallow and primarily anchors the plant.
Understanding the semantic connection between the two ideas is necessary to determine the correct logical transition.
2
Determine the logical relationship between these two ideas.
Since the plant gets water from its leaves, it does not require deep roots to access groundwater. Therefore, the shallow root system is a direct consequence of its leaf-based water absorption method, forming a cause-and-effect relationship.
Identifying the correct relationship allows you to choose a transition word that reflects this logic.
3
Evaluate the choices to find the transition that conveys cause-and-effect.
The option stating 'Consequently,' represents a cause-and-effect transition. The option 'NO CHANGE' represents an addition transition, 'However,' represents contrast, and deleting the transition leaves the causal link unexpressed.
Selecting the transition that matches the identified logical relationship ensures coherence and clarity in the text.
