Word Formation and Classification

The word 'USAGE' cannot be formed from 'ENCOURAGE' because 'USAGE' contains the letter 'S', which is missing from the source word. 'ANGER', 'GREEN', and 'COURAGE' can all be spelled using the available letters in 'ENCOURAGE'.

The word 'REASON' cannot be formed from 'CONCENTRATE' because 'REASON' contains the letter 'S', which is not present in the source word. 'CENTRE', 'CONCERN', and 'TREAT' only use letters found within 'CONCENTRATE'.

The statement is false. FLOCCINAUCINIHILIPILIFICATION does contain the letter 'e' (appearing three times: in the second, third, and fourth syllables: floccinaucinihilipilification). Therefore it is not the longest word without the letter 'e'.

The jumbled letters O-G-D can be rearranged to spell both 'dog' (d-o-g) and 'god' (g-o-d). Both are valid English words formed from these same three letters, making 'all of the above' correct.

The correct spelling is 'inexpressible' with an 'i' before the 'ble' suffix. In English, words ending in '-ible' (from Latin '-ibilis') include 'accessible,' 'audible,' and 'inexpressible.' Options A and C incorrectly use '-able' suffix, while 'nonexpressible' uses a different prefix entirely that changes the word's meaning.

The longest English word without repeating a letter is commonly cited as 'uncopyrightable' (15 letters), not 'copyrightable'. 'Copyrightable' itself does have no repeated letters, but it's not the longest - there are several longer words that fit this criteria.

The statement is false. 'Copyrightable' is not the longest word without repeating a letter - words like 'dermatoglyphics', 'uncopyrightable', and 'subdermatoglyphic' are longer and also have no repeated letters. The claimed answer 'False' is correct.

Several longer words exist without repeating letters, including "uncopyrightable" (15 letters), "dermatoglyphics" (15 letters), and "subdermatoglyphic" (17 letters). These are called isograms or heterograms. The claim about "copyrightable" being the longest is therefore incorrect.

The word 'uncopyrightable' (15 letters) can be written without repeating any letter, making it longer than 'copyrightable' (12 letters). Therefore, the statement claiming 'copyrightable' is the longest is incorrect.

Adding 'j' and 'a' creates: jealousy (green-associated), juvenile, jade (green stone), and jaundice (yellow, NOT green). The puzzle asks which completed word is NOT associated with green - jaundice is associated with yellow skin/eyes, making it the correct answer. This is a wordplay puzzle testing vocabulary.

The longest word in English without repeating a letter is 'uncopyrightable' (15 letters), not 'copyrightable'. Other long isograms (words with no repeated letters) include 'dermatoglyphics' (15 letters). The statement claims 'copyrightable' is the longest, which is factually incorrect.

'Copyrightable' has 11 letters without repetition, but 'uncopyrightable' has 14 letters and also has no repeating letters, making it longer. Other words like 'dermatoglyphics' (15 letters) also have no repeats, so the statement is false.

goto is reserved keyword (unused in Java), enum was added as keyword in Java 5, null is a literal keyword. These cannot be identifiers. extend is NOT a keyword (extends is keyword, but extend alone is valid identifier).

(3) Proem is introductory to any composition; others are persons.
