Question

1. part b: which answer explains why (refer to part a question #14)?

roots only work with prefixes
roots can stand alone without meaning
roots give the base meaning, just like foundations support buildings
roots are always greek

1. select two situations where a dictionary is more useful than a thesaurus:

locating antonyms
finding a more interesting synonym
checking a words pronunciation
confirming a words exact definition

Explanation:

• Question 16: Word roots give the base meaning of a word, similar to how foundations support buildings. They can combine with prefixes, suffixes, etc., but their core role is to provide the fundamental sense. For example, in the word "unhappy", "happ" (the root) gives the base meaning related to happiness.
• Question 17: A dictionary provides a word's pronunciation (e.g., using phonetic symbols like /ˈprəʊnʌnsiˈeɪʃn/) and its exact definition (e.g., "apple: a round fruit with red, green, or yellow skin and a white inside"). A thesaurus is mainly for synonyms (words with similar meanings) and antonyms (words with opposite meanings).

Answer:

• 16. Roots give the base meaning, just like foundations support buildings
• 17. Checking a word's pronunciation, Confirming a word’s exact definition
