study the following information carefully and answer the questions given below it. An exhibition is open for pubic since 9 am till 3 pm and again since 4 pm till 10 pm in a day. There are 12 batches of 1 hour each. The entry ticket bears a pass code made up of seven words, which changes every hour following a particular rule. The pass codes for 4 pm to 10 pm are same as those for respective hours during 9 am to 3 pm i.e., the pass code for 4 pm to 5 pm is same as that of 9 am to 10 am and so on. Following is an illustration of the code and steps of rearrangement for subsequent clock hours. First batch : 9 am to 10 am (4 pm to 5 pm) Pass code : dig more and you will find water Second batch : 10 am to 11 am (5 pm to 6 pm) Pass code : and dig find you water will more Third batch : 11 am to 12 noon (6 pm to 7 pm) Pass code : find and will you more water dig and so on. If the pass code for third batch is 'at study sleep and night child good', which batch will have the pass code 'child sleep night and study good at' ?
