Correct. The four words - diagnosis, paralysis, axis, and emphasis– follow the same rule while forming the plurals (change –is into –es) Thus, the plural forms of these words are - diagnoses, paralyses, axes and emphases. The word ‘alibis’ is an odd one here since it is already in the plural form. The word ‘alibis’ is the plural of the noun – alibi.

Correct. The four words - aquarium, medium, bacterium, and memorandum – follow the same rule while forming the plurals (by changing –um into –a). Thus, the correct plural forms of these words are - aquaria, media, bacteria and memoranda. (Though – aquariums, mediums and memorandums are also accepted.)The word ‘decorum’, though ending in –um, does not follow this rule of changing –um into -a. It forms the plural by adding –s.

Correct. The four words - oasis, analysis, basis, and crisis – follow the same rule while forming the plurals (by changing –is of the singular into -es). Thus, the plural forms of these words are - oases, analyses, bases and crises. The word ‘khakis’ is the odd one here since it is already in the plural form (khaki – khakis) and is not related to the rule mentioned above.

Correct. The four words - melody, territory, canopy, and army – follow the same rule while forming the plurals (by changing –y into –ies). (Rule: If the singular noun ends with -y and the -y has a consonant before it, change the -y into -ies to form the plural.) Thus, the plural forms of these words are – melodies, territories, canopies and armies. The word ‘valley’ is the odd one here since it ends with –y but has a vowel before the -y. In such a case, the plural is formed by simply adding –s to the singular noun.

Correct. There are no errors in the sentence. All the nouns have been used in their correct number.
