Answer: B. CBEDA
When arranging alphabetically, compare each word letter by letter from left to right. All entries start with 'Meg', so focus on the fourth letter: 'a' in Megaworld/Megawatt/Megaton, 'space' in Mega Sing, and 'p' in Meg Publishing. Words starting with 'Meg' followed by a space or 'p' come before 'Mega', and within those, 'Meg Publishing' (p) precedes 'Mega Sing' (space). Then order the 'Mega-' words: Megaton (to), Megaworld (aw), Megawatt (aw), with Megawatt before Megaworld by their sixth letters. The correct order is C-B-E-D-A.

All five words start with 'Tro', so you must compare the fourth letter: 'j' (Trojan) comes before 'n' (Troncales and Tronixmaster), and 'n' comes before 'p' (Trono). This gives the order: D (Trojan Securities Inc), B (Trojan Security Services), C (Troncales Freight International), E (Tronixmaster Sales and Service), A (Trono Enrique Associates), or DBCEA.

Between the 'Ultra-sa-' words, 'sales' comes before 'safety' (l before f in the third position). Between 'Ultrasecurity' and 'Ultraseer', 'security' comes before 'seer' (c before e in the fourth position after 'se'). The correct order is A, D, B, C, E.

- A.BDACE

- C.ABCDE
- D.DBCAE
- E.DBACE
Show answer & explanation
Answer: E. DBACE
To arrange alphabetically, compare each word letter by letter from left to right. All options start with 'Hope' or 'Hoppe', so we look at the fifth letter: 'w' comes before 'p', placing options A, B, C, D (Hopewell) before E (Hoppewell). Among the Hopewells, the sixth letter differs: 'w' (A), 'w' (B), 'w' (C), 'w' (D) are the same, so we continue to the seventh letter where 'e' (A, C), 'I' (B), 'l' (D) differ. Since 'I' comes after 'e' and 'l' comes after 'e', D comes last among Hopewells. Comparing A and C at the eighth letter: 'l' vs 'l' (same), then ninth letter: 'l' vs 'e', where 'e' comes before 'l', so C comes before A. The correct order is D, B, C, A, E.

This gives us C, D, B, E, A in alphabetical order.

- A.deabc
- B.debca
- C.dbeac
- D.dcbae
Show answer & explanation
Answer: D. dcbae
To alphabetize, compare each word letter-by-letter starting from the first letter. All five words begin with 'J', so we compare the second letter: Jaffa (a), Jericho (e), Jerusalem (e), Jesus (e), Jordan (o). Jaffa comes first. For the remaining four words starting with 'Je', we compare the third letter: Jericho (r), Jerusalem (r), Jesus (s), Jordan (r). Jesus comes fourth. Between Jericho and Jerusalem (both 'Jer'), we compare the fourth letter: Jericho (i) comes before Jerusalem (r). Finally, Jordan (o as third letter) comes last. The correct order is D-Jaffa, E-Jordan, B-Jericho, A-Jesus, C-Jerusalem, making the answer 'debac' which corresponds to option D.

- A.cabd
- B.cadb
- C.abdc
- D.abcd
Show answer & explanation
Answer: A. cabd
To alphabetize, compare the first letters of each word: Capitoline (C), Esquiline (E), Caelian (C), and Palatine (P). Since Capitoline and Caelian both start with C, compare their second letters: Capitoline has 'a' and Caelian has 'a', so compare the third letters where Capitoline has 'p' and Caelian has 'e'. This gives the order: Caelian (C), Capitoline (C), Esquiline (E), Palatine (P), or C-A-B-D.
