10In BCS Bengali Grammar (Bhasha & Byakaran), distinguish between Sadhu Bhasha and Chalito Bhasha, Sandhi vs. Samas, and Prakriti-Pratyay (Krit vs. Taddhit Pratyay).Sadhu Bhasha uses full long verb forms (koritechi) and pronoun forms (tahara) with heavy Tatsama (Sanskrit) vocabulary; Chalito Bhasha (popularized by Pramatha Chaudhuri in the journal 'Sabujpatra' in 1914) uses contracted spoken verb/pronoun forms and Tadbhava/Deshi words.

11In BCS General Science (Physics, Chemistry & Biology), why does ice float on water, which metal is liquid at room temperature vs. non-metal liquid at room temperature, and which gas is used in fire extinguishers vs. electric bulbs?Water reaches its MAXIMUM density (1 g/cm³) at 4°C; when it freezes into ice at 0°C, hydrogen bonding creates an open hexagonal crystal lattice that expands its volume by ~9% (density ~0.92 g/cm³), so ice floats on liquid water. Liquid metal at room temperature: Mercury (Hg; Gallium & Caesium melt near 28–30°C); Liquid non-metal at room temperature: Bromine (Br2). Fire extinguishers use Carbon Dioxide (CO2, often generated from NaHCO3 + H2SO4); incandescent electric bulbs are filled with inert Nitrogen or Argon gas to prevent oxidation/evaporation of the high-melting-point Tungsten (W) filament.
12In BCS Bangladesh Affairs (1971 Liberation War - Mujibnagar Government), when and where was the Provisional Government of Bangladesh (Mujibnagar Government) formed and sworn in, and what were the portfolios of its key leaders?Following the Historic 7th March Speech at the Racecourse Ground (now Suhrawardy Udyan, included in UNESCO's Memory of the World Register on Oct 30, 2017) and the Pakistani military crackdown ('Operation Searchlight') on the night of March 25, 1971, Independence was proclaimed on March 26, 1971.

14In BCS Geography & Disaster Management, why is Bangladesh highly vulnerable to Tropical Cyclones and Storm Surges in the Bay of Bengal, and during which two bimodal seasons do cyclones strike Bangladesh?Bangladesh's triangular funnel-shaped coastline at the northern apex of the Bay of Bengal, shallow continental shelf, flat low-lying deltaic topography (<10 m above sea level), and high tidal range amplify cyclonic storm surges. Cyclones in the Bay of Bengal follow a bimodal seasonal distribution before and after the Southwest Monsoon: 1. Pre-Monsoon (April–May, e.g., May 1991 Cyclone, Cyclone Mocha, Cyclone Remal) and 2.

25In BCS English Grammar (Clauses, Conditionals, Inversion & Prepositions), how do you identify a Noun Clause, an Adjective (Relative) Clause, and an Adverbial Clause in BCS Preliminary questions?Shortcut: Replace the entire underlined clause with the word 'IT'. If the sentence remains grammatically complete (acting as Subject, Object of a verb, Object of a preposition, or Complement), it is a NOUN CLAUSE (e.g., 'I know [where he lives]' -> 'I know IT'). If the clause immediately follows a Noun/Pronoun antecedent and answers 'which one?' (replaceable by an adjective), it is an ADJECTIVE (RELATIVE) CLAUSE (e.g., 'I know the place [where he lives]'). Note the classic BCS trap: in 'Wait here UNTIL I RETURN', 'until I return' modifies the verb 'wait' (answering when/how long) -> ADVERBIAL CLAUSE of time.
