Olympiad Test Level 2: Tense- 1 - Class 6 MCQ

The subject in these options is 'Ram and Sita'. The subject refers to two people, hence it is plural.
The verb must agree with the subject in person and number. (Called the subject-verb agreement)
When the subject is singular, the verb must be singular. When the subject is plural, the verb must be plural.
In option D, 'are' is a plural verb, that agrees with the plural subject 'Ram and Sita'. Hence option D is correct.
Option A: 'Plays' is in the third person singular form. It refers to a subject that is singular, whereas here it is plural.
Option B: 'Has' in 'has played' is singular. Its plural form is 'have', which is not present here.
Option C: Similarly, 'was' in 'was playing' is also singular. (The plural form is 'were'.)
These sentences are incorrect, as the verbs do not agree with the plural subject in each case.
Hence options A, B and C are incorrect.

The structure of Present Perfect Continuous tense is 'has/have + been + verb (ing) ', so the correct answer is 'She has been reading a book since morning'. 

Comes is the correct word to fit in the blank. The subject here, i.e. brother is singular. Thus, a singular verb should be used.
The action though talks about an incident that is happening in the present.
Example: Here, comes your birthday cake.
Thus, the word/verb 'comes' is used.

We are giving a general statement, so the correct tense form to be used is the Simple Present Tense. Hence, the correct answer is 'favours'.

The Correct verb is “have seen” in this sentence.

The Correct verb is “consider” in this sentence.

The Correct verb is “feel” in this sentence.

Here, 'have not seen' in the present perfect tense is correct because it is used to indicate an action which started in the past and has continued up until now. 
'Does not see' is grammatically incorrect.
'Am not seeing' in present continuous is incorrect because it implies an action going on at the time of speaking.
'Will not see' in future simple is incorrect because it indicates an action, condition or circumstance which has not taken place as yet.

The time period mentioned is 'for three days'. This shows that the girl was ill from the beginning till the end of three days. We do not have an indication that the girl is no longer ill. So, we may infer that the illness still continues to the present time. When we wish to show that an unfinished action started in the past and continues to the present, we use the present perfect tense. Hence, option C is the right answer. 
Option A may also be considered right since it simply shows that the 'girl being ill' is an event that occurred in the past. 

The past participle verb of "bet" is bet. Therefore option C is correct. Whereas, past participle of option A is beaten, option B is itself a past participle of beat and option D contains invalid word.

The past participle verb of "sow" is sown. Therefore, option D is correct. Whereas, option A is the base form of verb; option B is the past form of the verb; option C is an invalid word.
