Question

Select the word or phrase that best completes the following sentence: Desert flowers can be invisible for years ______ appear suddenly after heavy rain.

• A. alternatively or
• B. consequently and
• C. nevertheless, so
• D. actually, but

Hint:

When you see a sentence where the second half is the "opposite" of the first half (Invisible vs. Appear), always look for contrast markers like but, however, yet, or nevertheless.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
This question tests the logical application of conjunctions and adverbs within a compound sentence structure.
A sentence must maintain a coherent "logical flow."
Here, the sentence describes a biological phenomenon involving "desert flowers."
There is a stark contrast between two states: "being invisible for years" and "appearing suddenly."
The chosen words must bridge these two states in a way that emphasizes the surprise or the reality of the situation.
Step 2: Detailed Explanation:
Let's analyze why Option (D) is the most linguistically and logically sound choice:
1. "Actually" (Adverb of Emphasis): This word is used to emphasize the truth of a statement, especially when it might be hard to believe.
Because it seems impossible for flowers to be "invisible for years," the word "actually" validates this strange fact.
It sets up the reader for the surprising "reversal" that follows.

2. "But" (Contrastive Conjunction): This is the standard coordinating conjunction used to join two clauses that express opposite ideas.
"Invisible" is the opposite of "appearing."
The use of "but" creates a smooth transition between the dormant state of the flowers and their sudden blooming.

3. Why other options fail:
- Option (A) "alternatively or": This suggests a choice between two equal possibilities (e.g., "We can go by bus or alternatively by train").
Flowers don't choose; they transition from one state to another.
- Option (B) "consequently and": "Consequently" implies that the first state {caused} the second state.
Being invisible doesn't cause flowers to appear; the rain causes them to appear. This creates a logical fallacy.
- Option (C) "nevertheless, so": While "nevertheless" shows contrast, the word "so" implies a result.
The sentence "so appear suddenly" is grammatically incomplete because "so" usually introduces a clause that needs a subject (e.g., "so they appear").

Grammatically, Option (D) fits the rhythm and the logic of natural English speech perfectly.
Step 3: Final Answer:
The completed sentence should read: "Desert flowers can be invisible for years, actually, but appear suddenly after heavy rain."
