Q120. Which Bihar district lacks Dharwar-type geological formations among the options?
[65th BPSC Prelims (2019)]
(A) Munger
(B) Rohtas
(C) Jamui
(D) Nawada
Answer: (b) Rohtas
Explanation: Rohtas is mainly associated with Vindhyan formations, while Dharwar-age rocks occur in parts of southeastern Bihar, including areas around Munger, Jamui and Nawada. Identifying the geological province distinguishes older crystalline plateau terrain from Vindhyan sedimentary strata.
Mountain Ranges
Q119. Which central Indian hill sequence runs from west to east?
[UPPCS Prelims (2019)]
(A) Maikal–Satpura–Mahadeo–Chotanagpur
(B) Satpura–Mahadeo–Maikal–Chotanagpur
(C) Maikal–Mahadeo–Satpura–Chotanagpur
(D) Satpura–Mahadeo–Chotanagpur–Maikal

Glaciers
Q118. Which glacier–river pairs are correctly matched: 1. Bandarpunch–Yamuna 2. Bara Shigri–Chenab 3. Milam–Mandakini 4. Siachen–Nubra 5. Zemu–Manas?

(C) 2 and 5
(D) 3 and 5
Answer: (a) 1, 2 and 4
Explanation: Bandarpunch contributes to the Yamuna headwaters, Bara Shigri drains toward the Chenab, and Siachen feeds the Nubra system. Milam is linked to the Goriganga, not Mandakini, while Zemu drains the Teesta system rather than the Manas.

(A) Rohtang Pass
(B) Mintaka Pass

Mountain Passes
Q115. Which Sikkim–Tibet pass reopened for trade in 2006 after decades of closure?
[SSC CGL, 6 June 2019, Shift 1 (2019)]
(A) Lanak La

(D) Nathu La
Answer: (d) Nathu La
Explanation: Nathu La historically served caravans along routes connecting Sikkim and Tibet. Cross-border trade through the pass resumed in 2006 after prolonged closure following the 1962 conflict. Pensi La belongs to the Zanskar region rather than Sikkim.
Mountain Passes
Q114. Which mountain pass and location are incorrectly paired?
[SSC MTS, 7 August 2019, Shift 2 (2019)]
(A) Nathu La – Sikkim
(B) Shipki La – Arunachal Pradesh
(C) Zoji La – Ladakh region
(D) Mana – Uttarakhand

[SSC GD Constable, 1 March 2019, Shift 1 (2019)]
(A) Jelep La

(D) Dungri La
Answer: (d) Dungri La
Explanation: Dungri La, also called Mana Pass in some descriptions, is a very high motorable pass near Uttarakhand’s India–Tibet border. Records for highest motorable roads are revised as new routes open, so the answer belongs to the paper’s timeframe and options.
