Spearheading this challenging role was independent counsel Park Young-soo, whose leadership played a crucial role every time the inquiry into high-profile figures faced a dead end.

*inquiry: 조사, 수사
*high-profile: 시선이 집중되는
*face a dead end: 막다른 길로 몰리다
 The special team looking into the corruption allegations of President Park Geun-hye officially ended its term Tuesday, indicting most of its remaining key suspects before handing the case over to state prosecutors.
*hand over: 넘기다
 Its attempt to extend the investigation was thwarted upon the rejection of the request by acting President Hwang Kyo-ahn and opposition from the ruling conservative Liberty Korea Party.
 Despite the limitations it faced, in terms of time and jurisdiction, Park Young-soo’s special unit made pioneering steps in addressing the illegality of conglomerate chiefs and political big shots.
Military, Lotte conclude land swap contract for THAAD
 South Korea’s military and Lotte Group on Tuesday officially signed a contract to exchange the land needed to station a US missile defense system here, boosting efforts to accelerate the deployment despite mounting pushback from China.
*accelerate: 속력을 높이다
 In a written statement, the Ministry of Defense said the military had concluded the land-swap deal with Lotte Group, who handed over its golf course in the southeastern rural country of Seongju to host the Terminal High Altitude Area Defense system and received a state-owned military site near Seoul in return.
 Following the announcement, the ministry vowed to move up the deployment of THAAD and complete the process as soon as possible, although it did not offer a specific timeline. In November, Vincent Brooks, commander of the US Forces Korea, said the missile defense system would be deployed as early as July.
