Answer:
Survey data are collected by using all of these methods except Field Research.
Explanation:
In field research data has been gathered from different experiments, qualitative analysis and observations of any event.
On the other hand, survey data can be collected from Following:
<u>structured interview</u><u>:</u>
where data can be gathered by interviews and analyzed it on quantitative basis.
<u>Face to face questionnaires:</u>
Data has been collected by asking questions directly from users in the form of interview.
<u>self-administered questionnaires</u>
In this research, questionnaire has been designed to asked question related to some topic without conducting interview.

Answer:
There are multiple critical paths
Explanation:
The critical path method (CPM), or critical path analysis (CPA), is an algorithm for scheduling a set of project activities. It is commonly used in conjunction with the program evaluation and review technique (PERT). A critical path is determined by identifying the longest stretch of dependent activities and measuring the time required to complete them from start to finish.
The essential technique for using CPM is to construct a model of the project that includes the following:
- A list of all activities required to complete the project (typically categorized within a work breakdown structure),
- The time (duration) that each activity will take to complete,
- The dependencies between the activities and,
- Logical end points such as milestones or deliverable items.
Using these values, CPM calculates the longest path of planned activities to logical end points or to the end of the project, and the earliest and latest that each activity can start and finish without making the project longer. This process determines which activities are "critical" (i.e., on the longest path) and which have "total float" (i.e., can be delayed without making the project longer).
considering the above function of the cpm analysis because you have multiple path, there is tendency that more than path through the project network will have zero slack values.
