The pattern in the given sequence is that the first letter of each group is skipped, and the second and third letters of each group are repeated. Following this pattern, the missing group should have the second and third letters "J" and "O" repeated, and the first letter skipped. Therefore, the correct answer is "IJO".

Explanation

The pattern in the given sequence is that the first letter of each group is skipped, and the second and third letters of each group are repeated. Following this pattern, the missing group should have the second and third letters "J" and "O" repeated, and the first letter skipped. Therefore, the correct answer is "IJO".

2. Nicio pasare nu este patruped:Toate vrabiile sunt pasari

Unele vrabii sunt patrupede

Nicio vrabie nu este pasare calatoare

Unele vrabii mananca seminte de grau

Nicio vrabie nu este patruped

The given answer states that "Nicio vrabie nu este patruped" which translates to "No sparrow is a quadruped." This answer is correct because the given statement "Toate vrabiile sunt pasari" translates to "All sparrows are birds," which implies that sparrows cannot be quadrupeds since birds are not quadrupeds. Therefore, it can be concluded that no sparrow is a quadruped.

Unii adolescenti au prieteni delincventi.

Toti adolescentii incalca legea.

Unii adolescenti incalca legea.

Unii dlincventi nu cunosc legea.

The given correct answer is "Unii adolescenti incalca legea." This can be inferred from the statements "Unii delincventi sunt adolescenti" (Some delinquents are adolescents) and "Toti delincventii incalca legea" (All delinquents break the law). Since some delinquents are adolescents and all delinquents break the law, it can be concluded that some adolescents break the law.

The pattern in the given sequence is that each group of three letters is formed by taking the first letter, skipping the second letter, and taking the third letter. For example, in the first group ABA, we take the first letter A, skip the second letter B, and take the third letter A. Applying this pattern to the last group GHO, we take the first letter G, skip the second letter H, and take the third letter O. Therefore, the next group should be formed by taking the first letter I, skipping the second letter J, and taking the third letter U. Hence, the correct answer is IJU.

21. Arii si Darii sunt doua triburi rivale. Fiecare dintre ei incearca sa captureze cat mai multi membrii ai tribului inamic. Stiind ca, indiferent de conditii, toti Darii dorm numai 5 ore pe noapte, Arii au atacat satul atunci cand acestia dormeau si au capturat 10 prizonieri. Dupa 3 zile, seful tribului Ari observa ca toti prizonierii dorm mai mult de 5 ore pe noapte. Care este concluzia care poate fi dedusa cu necesitate din informatiile de mai sus?

Niciun prizonier nu este Dari

Unii prizonieri sunt Dari

Toti priezonierii sunt Dari

Unii prizonieri nu sunt Dari

The conclusion that can be deduced from the given information is that no prisoner is a Dari. This can be inferred because the Ari tribe attacked the village when the Dari people were sleeping, and they captured 10 prisoners who are now observed to be sleeping more than 5 hours per night. Since all Dari people only sleep 5 hours per night, it can be concluded that none of the prisoners are Dari.

The given sequence follows a pattern where each number is obtained by subtracting the previous number from the square of its position in the sequence. For example, the first number 3 is obtained by subtracting 0 from the square of its position (1^2). Similarly, the second number 6 is obtained by subtracting 1 from the square of its position (2^2), and so on. Therefore, the missing numbers in the sequence are obtained by subtracting the previous numbers from the squares of their positions. Hence, the missing numbers are 38 and 51.

Therefore, flight 104 takes off at 10:00, flight 106 takes off at 11:00, and flight 107 takes off at 12:00. Since flight 105 takes off later than flights 103 and 102, and flight 106 takes off at 11:00, it can be concluded that flight 105 takes off at 15:00, the last available hour in the given time interval.

37. In urma unor conditii meteorologice extreme, aeroportul din Londra a decis ca va reduce numarul avioanelor care decoleaza. Au permis de decolare numai cursele 101, 102, 103, 104, 105, 106, 107. Decolarea are loc din ora in ora in intervalul 09:00 si 15:00 si se tine cont de urmatoarele restrictii Cursa 101 trebuie sa decoleze la ora 09:00 Cursa 105 decoleaza mai tarziu decat cursele 103 si 102 Avioanele 104, 106 si 107 decoleaza in aceasta ordine, la ore consecutive. Daca cursa 106 decoleaza la ora 14:00, atunci la ce ora va decola cursa 105?

Based on the given conditions, we can determine the order of departure for the flights. Flight 101 departs at 09:00, followed by flight 102, flight 103, and then flight 105. Flight 105 departs later than flights 103 and 102. Flight 106 departs at 14:00, and flight 107 departs after flight 106. Since flight 105 departs after flights 103 and 102, and flight 106 departs at 14:00, the only available time slot for flight 105 is 12:00. Therefore, the answer is 12:00.

The pattern in the given sequence is that each number is the product of the two previous numbers. For example, 4 * 8 = 32, 8 * 16 = 128, and so on. Therefore, the missing numbers should be the product of 5 and 10, which is 50, and the product of 10 and 25, which is 250. Thus, the missing numbers are 50 and 250.

The given sequence follows a pattern where each number is multiplied by itself to get the next number. For example, 1 * 1 = 1, 2 * 2 = 4, 4 * 4 = 16, and so on. Following this pattern, the missing numbers are 8 * 8 = 64 and 7 * 7 = 49. Therefore, the missing numbers are 64 and 49, with the corresponding number of 8.

The flight 102 can depart at the latest at 14:00 because it is stated that flight 105 departs later than flights 103 and 102. Since flight 105 is included in the list of allowed departures, it means that flights 103 and 102 must depart before 105. The given time interval for departures is from 09:00 to 15:00, and the flights must depart consecutively. Therefore, the latest possible time for flight 102 to depart is 14:00.

The given pattern shows a sequence of numbers where each number is the sum of the two numbers directly above it. Starting from the top, the first number is 90, the second number is 1, and so on. Therefore, the missing numbers can be calculated as follows: 90 + 1 = 91 1 + 81 = 82 81 + 2 = 83 2 + 63 = 65 63 + 3 = 66 3 + 91 = 94 91 + 82 = 173 82 + 83 = 165 83 + 65 = 148 65 + 66 = 131 66 + 94 = 160 94 + 173 = 267 173 + 165 = 338 165 + 148 = 313 148 + 131 = 279 131 + 160 = 291 160 + 267 = 427 267 + 338 = 605 338 + 313 = 651 313 + 279 = 592 279 + 291 = 570 291 + 427 = 718 Therefore, the missing numbers are 36 and 4.

The given sequence follows a pattern where each number is obtained by multiplying the previous number by 2 and subtracting 10. The pattern can be observed as follows:

3 * 2 - 10 = 4
4 * 2 - 10 = 6
6 * 2 - 10 = 10
10 * 2 - 10 = 18
18 * 2 - 10 = 34
34 * 2 - 10 = 66

Therefore, the missing numbers in the sequence are 34 and 66.

44. S-a constatat ca toate ciupercile otravitoare identificate pana in prezent produc o substanta numita platistena, deoarece aceasta ar necesita un sol bogat in fier. In schimb toate ciuepercile otravitoare produc hircon. Care este concluzia care poate fi dedusa cu necesitate din afiramtiile prezentate?

Toate ciupercile ortravitoare produc atat hircon cat si platistena .

Unele ciuperci otravitoare produc atat hircon cat si platistena .

Nicio ciuperca otravitoare care produce hircon nu produce platistena .

Unele ciuperci otravitoare care produc hircon nu produc platistena.

The conclusion that can be deduced from the given statements is that some poisonous mushrooms that produce hircon do not produce platistena. This conclusion is based on the fact that all poisonous mushrooms identified so far produce platistena, and since hircon requires a soil rich in iron, it can be inferred that there are some poisonous mushrooms that do not produce platistena but still produce hircon.
