3. Exemplos de Flashcards de Alto Rendimento (Japanese JLPT N5–N1 Kanji, Vocabulary & Grammar )

Nível	Frente (Pergunta / Termo)	Verso (Resposta / Explicação)
basic	In Japanese Kanji, what is the difference between On'yomi (音読み) and Kun'yomi (訓読み), and when is each typically used?	On'yomi (音読み) is the Sino-Japanese reading derived from historical Chinese pronunciation, typically used in multi-kanji compound words (熟語, jukugo) such as 水道 (suidō) or 山脈 (sanmyaku). Kun'yomi (訓読み) is the native Japanese reading attached to a single standalone kanji or a kanji followed by hiragana okurigana, such as 水 (mizu), 山 (yama), or 食べる (taberu).
basic	In JLPT N5/N4, what is the grammatical difference between the topic marker は (wa) and the subject marker が (ga)?	は (wa) marks the overarching discourse topic ('as for X...'), known information, or a contrast between two items. が (ga) identifies the specific grammatical subject of an action/state, introduces new or unknown information, follows question words as subjects (誰が来ますか — Who is coming?), and marks objects of ability/desire/liking (日本語がわかる, 寿司が好きだ).
basic	Distinguish the three categories of Japanese Keigo (敬語): 丁寧語 (Teineigo), 尊敬語 (Sonkeigo), and 謙譲語 (Kenjougo), including the Uchi-Soto (内・外) rule.	丁寧語 (Teineigo: です/ます, ご/お prefixes) is polite speech directed to the listener. 尊敬語 (Sonkeigo) elevates the subject's actions/belongings and is used for superiors, clients, and out-group (外, soto) people. 謙譲語 (Kenjougo) humbles the actor's own actions to elevate the recipient and is used for oneself AND for one's own company/family in-group (内, uchi—even one's own company president!) when speaking to an outside client.
basic	What are the productive regular formulas for converting a normal verb into 尊敬語 (Sonkeigo) vs 謙譲語 (Kenjougo)?	For 尊敬語 (Sonkeigo): 1. お + Verb Masu-stem + になる (お読みになる, お待ちになる), or 2. Passive form ～(ら)れる (読まれる, 来られる). For 謙譲語 (Kenjougo): お + Verb Masu-stem + する / いたす (お持ちする, ご案内いたします — for Sino-Japanese する nouns, use ご + Noun + する/いたす).
intermediate	State the three core Mandarin Chinese Tone Sandhi (变调) rules for Third Tones (3rd + 3rd), 不 (bù), and 一 (yī) tested in HSK.	1. Third-Tone Sandhi: When two 3rd-tone syllables occur consecutively, the first shifts to a 2nd tone (你好 nǐ + hǎo -> ní hǎo). 2. 不 (bù): Pronounced 4th tone (bù) before 1st, 2nd, and 3rd tones, but shifts to 2nd tone (bú) before another 4th tone (不是 bú shì, 不去 bú qù). 3. 一 (yī): Pronounced 1st tone (yī) when counting, ordinal, or at the end of a word; shifts to 2nd tone (yí) before a 4th tone (一个 yí gè, 一定 yí dìng); shifts to 4th tone (yì) before 1st, 2nd, or 3rd tones (一天 yì tiān, 一起 yì qǐ).
intermediate	In Hanyu Pinyin orthography, when are the umlaut dots over 'ü' dropped (written simply as 'u') vs kept?	The vowel 'ü' keeps its two dots after 'l' and 'n' to distinguish 'lü' (绿) and 'nü' (女) from 'lu' (路) and 'nu' (努). After the palatal initials 'j', 'q', and 'x' (and when preceded by 'y' as 'yu'), the two dots are ALWAYS dropped in writing because 'j/q/x/y' never combine with plain 'u': thus 居 (jū), 去 (qù), 学 (xué), and 鱼 (yú) all have the underlying 'ü' vowel.
intermediate	In Korean phonology, what are the 7 representative syllable-final consonant sounds (받침, Batchim Neutralization / 음절의 끝소리 규칙) when a syllable is pronounced in isolation or before a consonant?	Every Korean final consonant neutralizes to one of 7 unreleased stops/nasals/liquid: 1. [ㄱ] (ㄱ, ㄲ, ㅋ); 2. [ㄴ] (ㄴ); 3. [ㄷ] (ㄷ, ㅌ, ㅅ, ㅆ, ㅈ, ㅊ, ㅎ); 4. [ㄹ] (ㄹ); 5. [ㅁ] (ㅁ); 6. [ㅂ] (ㅂ, ㅍ); 7. [ㅇ] (ㅇ). For example, 꽃 (flower), 옷 (clothes), and 낮 (daytime) all end with the unreleased [ㄷ] sound in isolation.
intermediate	Explain Korean Liaison (연음화) vs Aspiration (격음화) when a Batchim is followed by a vowel or ㅎ.	1. Liaison (연음화): When a syllable ending in a consonant (except ㅇ or ㅎ) is followed by a grammatical particle/ending starting with silent ㅇ (vowel), the original consonant shifts smoothly into the next syllable's initial onset position: 한국어 -> [한구거], 꽃이 -> [꼬치], 밖에 -> [바께]. 2. Aspiration (격음화): When ㄱ, ㄷ, ㅂ, or ㅈ meets ㅎ (in either order), they merge into aspirated ㅋ, ㅌ, ㅍ, or ㅊ: 좋다 -> [조타], 입학 -> [이팍], 축하 -> [추카].
advanced	In NCERT Class 11 Biology (Cell Cycle & Division), list the exact five sub-stages of Prophase I of Meiosis I in sequential order and the key cytological event occurring in each.	1. Leptotene: Chromosomes gradually condense and become visible under the light microscope (bouquet stage). 2. Zygotene: Homologous chromosomes pair up (synapsis) forming a bivalent/tetrad stabilized by the Synaptonemal Complex. 3. Pachytene: Crossing over (genetic recombination) occurs between non-sister chromatids of homologous chromosomes at Recombination Nodules via the enzyme Recombinase. 4. Diplotene: Dissolution of the synaptonemal complex except at X-shaped crossover sites called Chiasmata. 5. Diakinesis: Terminalisation of chiasmata, nucleolus disappears, and nuclear envelope breaks down.
advanced	Compare C3, C4 (Hatch-Slack), and CAM plants in NCERT Plant Physiology with respect to primary CO2 acceptor, primary carboxylation enzyme, first stable product, and Kranz anatomy.	1. C3 Plants: Primary acceptor is 5-carbon RuBP in mesophyll cells via RuBisCO; first stable product is 3-C 3-PGA; no Kranz anatomy; photorespiration is high. 2. C4 Plants (maize, sorghum, sugarcane): Primary acceptor is 3-carbon PEP in mesophyll cells via PEPcase (which lacks oxygenase activity), forming 4-C Oxaloacetic Acid (OAA); decarboxylated in thick-walled Bundle Sheath cells (Kranz anatomy) where RuBisCO fixes CO2 with zero photorespiration. 3. CAM Plants: Temporal separation (stomata open at night fixing CO2 via PEPcase into malic acid stored in vacuoles; Calvin cycle runs during the day).
advanced	In JEE Calculus, state Newton-Leibniz's Rule for differentiating a definite integral with variable limits, and the King's Property + Queen's Property of definite integrals.	1. Leibniz Rule: d/dx [∫_{g(x)}^{h(x)} f(t) dt] = f(h)·h'(x) − f(g)·g'(x). 2. King's Property: ∫_a^b f(x) dx = ∫_a^b f(a + b − x) dx (especially ∫_0^a f(x) dx = ∫_0^a f(a − x) dx). 3. Queen's Property: ∫_0^{2a} f(x) dx = ∫_0^a [f(x) + f(2a − x)] dx, which equals 2∫_0^a f(x) dx if f(2a − x) = f(x) and 0 if f(2a − x) = −f(x). Also, Wallis's Formula: ∫_0^{π/2} sin^n(x) dx = ∫_0^{π/2} cos^n(x) dx.
advanced	In JEE Differential Equations & Linear Algebra, state the Integrating Factor (I.F.) and solution of a first-order linear ODE, and Cayley-Hamilton Theorem + rank-nullity conditions for a system of linear equations AX = B.	1. For dy/dx + P(x)y = Q(x), the Integrating Factor is I.F. = e^(∫P(x)dx), and the general solution is y · (I.F.) = ∫ Q(x) · (I.F.) dx + C. 2. Cayley-Hamilton Theorem: Every square matrix A satisfies its own characteristic equation det(A − λI) = 0 (where Σ λ_i = Trace(A) and Π λ_i = det(A)). 3. Rouché-Capelli Theorem for AX = B (n variables): Consistent with a unique solution if rank(A) = rank([A|B]) = n; Consistent with infinitely many solutions if rank(A) = rank([A|B]) < n; Inconsistent (no solution) if rank(A) ≠ rank([A|B]).
