Test: Adjectives- 1 - Class 5 MCQ

In the first blank, the use of the definite article 'the' suggests twe need to use the superlative degree of adjective. Hence, the answer will be 'oldest'. In the second blank, the use of 'as...as' structure requires the use of positive degree of adjective so the answer is 'innocent'.

The comparison is between the act of 'going outdoors' and 'reading'. The question asks for the Gerund 'reading' to be replaced with the correct answer. In the first part of the sentence, the phrase is made up of an infinitive and a noun 'to go outdoors'. Since we're comparing two activities, we need to write the second activity in the same form, i.e, 'to read at home.' Hence option A is correct and option D is incorrect. 'Reads' is a present indicative verb and isn't the correct answer. 'Having read' is a participle and what we need is an infinitive, hence this is an incorrect answer.

The phrases in a comparison sentence should both be parallel in structure as well as in context. Here there are two superlatives concerning the same noun 'giraffe' in comparison with the other animals. The underlined superlative 'best' attributes the meaning 'desirable quality', which is incorrect in the context of the sentence as it's a quality in terms of personality, and it's not relevant here. Hence option D is incorrect. The phrase 'largest ruminant' suggests that we're describing the noun 'giraffe' in terms of its size, the only relevant option is Option A, which modifies the noun 'terrestrial animal' in terms of height, hence option A is correct. Option B is incorrect because it's a comparative, whereas the noun calls for a superlative. Similarly, option C is incorrect because 'herbivorous' is not a superlative adjective.

The sentence is comparing how good Jim is at painting to how good he is at dancing. The words/phrases that are being compared should have the same grammatical form. This is called parallelism. Hence, the right answer is option D. 

In the given sentence, the use of "other" is incorrect, because we want to convey that she is the 'most' promising among all the students. When we use 'other', she is excluded from the comparison with the students. Thus, option D is correct.
Option A and B are incorrect, as due to the use of 'other', she is excluded from the comparison with other students.
Option C is incorrect, because the use of 'more' denotes that she is the more promising students than others, but it doesn't mean that she is the most promising, which is something that the given question wants to convey.

Many adjectives are formed from a base of a different class with a suffix (e.g. -less, -ous). Adjectives can also be formed from other adjectives, especially by the negative prefixes (un-, in- and non-). The most common suffixes are -al, -ent, -ive, -ous, -ful, -less. Disaster is a noun meaning a sudden accident or a natural catastrophe that causes great damage or loss of life. Adjective of this noun would define something that causes great danger. From the above-given form of prefix and suffix, "-ous" is one of the suffixes which are present in the options.
Disaster + ous = Disastrous

The adjective form of the verb 'accept' is: acceptable.
Hence, Option A is correct.
'Acceptable' is an adjective that modifies the noun "behaviour".
Option B: 'Acceptance' is the noun form of the word in brackets. Since the question asks for the adjective, this option is wrong. Also, a noun cannot modify another noun 'behaviour'.
Option C: Similarly, 'acceptability' is a noun. Hence C is incorrect.
Option D: The word in brackets is a verb. It refers to an action, whereas the question calls for an adjective. Hence D is incorrect.

In the given sentence, 'the systems of classification' of the Library of Congress and the Dewey Decimal are spoken about. 'The system of classification of the Library of Congress' is to be replaced by 'the system of classification of the Dewey Decimal. 'That' is a demonstrative used to refer back to an entire phrase or sentence. Here, 'that' is being used to replace the phrase 'system of classification' in the second half of the sentence, hence option A is correct. This phrase is not being replaced by 'the Dewey Decimal' itself, so option D is incorrect, even by eliminating 'the' in option C, it's still incorrect. 'Those' refers to plural nouns since we are comparing the system of classification (singular noun) we need a singular demonstrative pronoun, not a plural one, which makes option B incorrect.

Many adjectives are formed from a base of a different class with a suffix (e.g. -less, -ous). Adjectives can also be formed from other adjectives, especially by the negative prefixes (un-, in- and non-). The most common suffixes are -al, -ent, -ive, -ous, -ful, -less. Delight is a noun which means something that gives great pleasure or enjoyment. Option C gives the correct used adjective (It describes something that is greatly pleasing). In this case, the suffix is -ful as mentioned earlier in this solution. 
delight + ful = delightful
Option C is the correct option

Adjectives are the words which modify the noun. Adjectives can be formed from nouns. 'Fortune' is a noun and adjective can be formed by adding 'ate' at the end of the word and removing 'e' from the word 'fortune'. Thus, option B is the correct answer.
