Concept:Match sentence fragments from Column 1 with Column 2 to form grammatically and contextually correct sentences.
Explanation:Examine each possible pairing carefully.
Pair A-D: "The latest summit among the USA and North Korea will be a litmus test for the stalled negotiations..." — The word "among" is incorrect for two entities; "between" should be used. So this pair is invalid.
Pair B-F: "This week's summit is intended to craft concrete steps to implement the Panmunjom Declaration, named after the border village." — Both grammar and context are correct.
Pair C-E: "The institution was sanctioned by the U.N. Security Council last year as a part of global efforts." — This combination is also grammatically and contextually correct.
Thus the only valid pairs are B-F and C-E.
In the options, these pairs are represented as E-C (Column 2 E with Column 1 C) and F-B (Column 2 F with Column 1 B).
Option E states "Only E-C and F-B", which exactly matches the valid pairs.
Answer:Option E: Only E-C and F-B
