Question

In the given tree-structure NP1 C-commands NP2 but not vice versa because:

• A. C-command cannot be a reciprocal relationship
• B. No node dominates both NP2 and NP1
• C. VP1 dominates NP2 and C-commands NP1
• D. VP1 dominates NP2 but not NP1

Hint:

In syntactic tree structures, C-command and dominance are key concepts in understanding relationships between elements. VP1 dominates NP2 and C-commands NP1, but VP1 does not dominate NP1 directly.

Answer 1

The Correct Option is C, D

Step 1: Analyze the tree structure.
In the given tree structure, NP1 is the noun phrase "Every alien," while NP2 is the noun phrase "ET." The structure illustrates that NP1 and NP2 are connected through different parts of the tree.
Step 2: Analyzing the options.
- (A) C-command cannot be a reciprocal relationship: This is not relevant because the issue at hand is about dominance and C-command, not reciprocity.
- (B) No node dominates both NP2 and NP1: This is incorrect because VP1 dominates NP2 and C-commands NP1.
- (C) VP1 dominates NP2 and C-commands NP1: This is correct because VP1 dominates NP2, and as a result, it C-commands NP1.
- (D) VP1 dominates NP2 but not NP1: This is also correct because VP1 dominates NP2, but it does not dominate NP1, which explains the non-reciprocal C-command relationship.

Step 3: Conclusion.
The correct answers are (C) and (D), as they are both supported by the tree structure.
