Error Identification

'conducive to'
Conducive is used in conjunction with the preposition ‘to’. 

‘Unless you’
Unless is similar in meaning to ‘if not’. So, using two negatives will change the meaning of the sentence.

Instead of 'steam', there should be 'steamed'.

‘have been obscured’ is correct. ‘The issues’ denotes that the subject is plural. Hence, the plural form of the verb is to be used.

‘spoke clearly’
We are describing the way ‘he’ spoke. So, adverb ‘clearly’ is to be used with the verb ‘spoke’.

‘hill station is’
‘Although it is summer’ indicates present tense. So, we need to maintain the same form of tense in the whole sentence.

‘Everyone tried his luck’
Everyone is singular and hence, singular pronoun is to be used.

'Inspite of' is the correct answer. 

‘The obstacles which’ is correct.
The use of ‘to’ is unnecessary in the sentence.

‘which frequently root us’
As we are talking about emotions in plural and fear is one example, so ‘root’ will be used.

‘Of the danger’ is the correct usage. Warning a person of the situation. ‘Of’ is used for reference/relating to some context . So, we use ‘of’. 

‘I am certain that neither’
We use ‘neither’ with two.

‘Sitting in the shade’
Wrong use of the preposition ‘under’. We sit ‘in’ the shade not ‘under’ the shade.

‘where I had’
Wrong placement of the pronoun ‘I’. ‘I had kept’ is the proper sentence of past perfect .

‘One should look for one’s’
‘One’ is gender neutral and its possessive form is also ‘one’s’. Generally, we do not useany other pronoun with it.

‘The vehicle stopped’
The above phrase describes what the police stopped. If we use ‘is’, we need to have a conjunction to join the second part with the first part.

‘Looked upon’ means to consider someone in a particular way. Here we are examining before replying. Hence, 'looked at me' would make it correct.

‘the picnic’
‘Its’ is used for inanimate objects. Here the person is hiring the bus for a particular reason. So, ‘the’ will be used instead of ‘its’.

There is no error in the sentence.

‘also Agra’
Use of ‘to’ is not required with also.

"were" instead of "was"

‘are studied not only’
There is error of parallelism. Comparison is being made between 'studies in European countries' and 'oriental countries'. But we compare like things. There is no other option for ‘studied’…so we use ‘not only’ after ‘studied’ and before ‘in European countries’.
