Difficulty: Very hardLiteral Comprehension and Fact Retrieval

Read the passage below carefully and evaluate the statement that follows.

In the coastal wetlands of the Niger Delta, ecological restoration projects have targeted the invasive Nypa palm (Nypa fruticans), which rapidly colonizes brackish mudflats and displaces indigenous red mangroves (Rhizophora mangle). Introduced from Singapore in 1906 to control beach erosion, Nypa palms feature shallow root systems that fail to bind coastal sediments effectively, accelerating shoreline recession. Restoration teams systematically eradicate dense Nypa stands before manually outplanting nursery-reared Rhizophora seedlings. Field assessments conducted between 2021 and 2024 revealed that while clear-cutting Nypa palms restored tidal hydrology within six months, full soil stabilization required at least three years of established Rhizophora root architecture. Furthermore, crab predation on young seedlings initially reduced survival rates by forty percent until protective mesh guards were installed.

Statement: Shoreline erosion accelerated primarily because the shallow root architecture of indigenous red mangroves failed to bind coastal sediments after their introduction from Singapore in 1906.

Answer: Answer

Answer

False
The correct response is False because the text explicitly identifies the invasive Nypa palm—not the indigenous red mangrove—as the species introduced from Singapore in 1906 with shallow roots that accelerate shoreline erosion.

Step-by-Step Solution

1
Analyze the statement to identify the key factual claims made about red mangroves.
The statement claims that red mangroves were introduced from Singapore in 1906 and possess shallow root systems that accelerate shoreline erosion.
Deconstructing the statement into distinct factual claims allows direct verification against explicit text evidence.
2
Locate explicit passage evidence regarding the origins and root characteristics of the species mentioned.
The passage states that Nypa palms (not red mangroves) were introduced from Singapore in 1906 and feature shallow root systems accelerating shoreline recession, while red mangroves are indigenous.
Literal comprehension requires verifying entity-attribute pairings directly from the text without misattributing traits across subjects.
3
Compare statement claims against explicit passage facts to determine truth value.
The statement conflates the attributes of the invasive Nypa palm with those of the indigenous red mangrove, rendering the statement objectively false.
A statement is false if any explicit fact within it directly contradicts the authoritative text.
