Articles & Nouns

'Honest' begins with a silent 'h' — the vowel sound /ɒ/ follows, so use 'an'. 'Decade' begins with the consonant sound /d/, so use 'a'. Article choice is based entirely on the initial SOUND of the next word, not its spelling. 'An honest' is correct; 'a honest' is the classic NDA error.

'One' begins with the /w/ consonant sound — use 'a one-man army'. 'MBA' is read letter by letter as 'em-bee-ay' — it begins with the vowel sound /em/ — use 'an MBA'. Both words trap students: 'one' looks like a vowel; 'M' looks like a consonant. Sound decides — not spelling.

Rivers take 'the' — The Ganga. Superlatives take 'the' — the holiest. Country names (singular) take no article — India, not 'the India'. Option A adds 'the' before India — wrong. Option B misses 'the' before Ganga and the superlative. Option D misses 'the' before the superlative 'holiest'.

Single mountain peaks never take 'the' — write 'Mount Everest', not 'The Everest'. 'The Himalayas' is correct — mountain ranges always take 'the'. 'The Asia' is also wrong — continents never take 'the', but among the options, A contains the most direct error. The correct sentence: 'Mount Everest is the highest peak in the Himalayas and Asia.'

'University' begins with the /j/ (y) consonant sound — not a vowel sound — so use 'a university'. 'MBA' is read as 'em-bee-ay' beginning with the vowel /em/ — use 'an MBA'. The letter 'u' looks like a vowel but sounds like 'you' (consonant). This is the single most tested a/an trap in NDA English.

Oceans always take 'the' — the Pacific is correct. Option A: individual peaks take no 'the' — Mount Everest, not 'the Mount Everest'. Option C: country names (singular) take no 'the' — France, not 'the France'. Option D: languages never take 'the' — 'French and German', not 'the French and the German'.

Sports and games never take 'the' — 'plays cricket', not 'plays the cricket'. 'The dinner' is also wrong — meals do not take 'the' in standard use ('after dinner', not 'after the dinner'). However, 'the cricket' is the more direct, classically tested error. The correct form: 'He plays cricket every evening after dinner.'

All three blanks require 'the'. 'The sun' — unique celestial body, only one exists. 'The east' and 'the west' — specific, unique directional references always take 'the'. Unique or one-of-a-kind nouns and fixed directional references always use the definite article. All three are correct with 'the'.

'Advice' is uncountable — it has no plural and cannot take 'a/an'. Saying 'an advice' or 'advices' is always wrong. Correct forms: 'a piece of advice', 'some advice'. 'Suggestion', 'report', and 'officer' are countable nouns — they take 'a/an' and have plural forms normally. Other common uncountable nouns: information, luggage, furniture, equipment, news.

'Information' is an uncountable noun — it has no plural form. 'Informations' is always wrong. The correct form is 'much information' or 'a great deal of information'. Other uncountable nouns that students wrongly pluralise: advice, furniture, luggage, equipment, knowledge, news, progress, scenery.

When a collective noun acts as a single unified body, it takes a singular verb: 'The fleet was sailing' — correct. Option A: 'have reached their individual decisions' implies members acting separately, so plural could work, but 'individual decisions' is contradictory (a jury reaches one verdict). Option C: 'arguing each other' — wrong idiom (arguing with each other). Option D: 'as a unit' means unified — singular 'was ordered' required.

'Eye' begins with the vowel sound /aɪ/ — use 'an eye'. 'Ability' begins with the vowel sound /ə/ — use 'an ability'. Both are first mentions with no prior context, so the indefinite article is needed for both. Both words begin with vowel sounds, making 'an' correct for both blanks.

'Cattle' is always plural — it never takes 'a/an' and always takes a plural verb. 'A cattle' is wrong on both counts. The correct form is simply 'Cattle were grazing'. Similarly: 'people', 'police', 'clergy' are always plural. 'Cattle' has no singular form — one animal is 'a cow', 'a bull', or 'a calf'.

Abstract nouns used in a general sense take no article — 'Courage is the foundation of leadership.' Option A: 'honesty' used universally takes no article — 'Honesty is the best policy.' Option B: 'life' used generally takes no article — 'Life is full of surprises.' Option D: abstract uncountable nouns like 'courage' cannot take 'a/an'. Only C is correct.

'The Ganga' — rivers always take 'the'. 'A sacred river' — first mention, non-specific, countable → 'a'. 'Northern India' — general geographical areas (not specific institutions or unique entities) take no article. 'The northern India' would be wrong. Option B (with dash = no article before 'northern India') is correct.

'The honest man' implies a specific, previously identified man. But the sentence introduces him for the first time — so the indefinite article is needed: 'He is an honest man'. Note: 'honest' starts with silent 'h' → vowel sound → 'an'. 'The' is only used when both speaker and listener know exactly which person is meant — that condition is not met here.

Musical instruments take 'the' when referring to the act of playing them — 'the violin', 'the piano', 'the guitar'. Option A: 'a violin' suggests any random violin, not the instrument as an art. Option B: no article is wrong — the instrument requires 'the'. Option D: 'that violin' implies a specific previously mentioned violin — not appropriate in a general statement about her skill.

'The best cadet' — superlatives always take 'the'. 'The batch' — specific, contextually known batch. 'The Sword of Honour' — a unique, specific award that both speaker and listener know — takes 'the'. All three blanks require 'the': superlative, specific reference, and unique award.

'An most experienced' is wrong in two ways: superlatives always take 'the', not 'an'; and 'most' with a following adjective forms a superlative that requires 'the'. The correct form is 'the most experienced nurse'. 'An' is used before vowel sounds for indefinite references — never before a superlative.

'A special mission' — first mention, non-specific, countable singular noun begins with consonant /s/ → 'a'. 'An extraordinary courage' — wait: 'courage' is uncountable and takes no article. But in this expression 'extraordinary courage' refers to the quality in general — no article needed. Among the options, A with 'a … an' is the intended answer: 'a special mission' (consonant start) and 'an extraordinary' (vowel start /ɛ/).
