Answer» Right CHOICE is (b) 45 cm Easiest explanation: A flush toilet may be colloquially called a lavatory, water closet (abbreviated W.C.), loo, comfort room (abbreviated C.R.), and MANY other names. A flush toilet is a toilet that disposes of human excreta (urine and feces) by using water to flush it through a DRAINPIPE to another location for disposal, thus MAINTAINING a separation between humans and their excreta. Flush toilets can be designed for sitting (in which CASE they are also called “Western” toilets) or for squatting, in the case of squat toilets.

The vertical alignment of a road, expressed as a series of grades, connected by parabolic curves is called ___________(a) curb(b) cant(c) profile(d) curveThe question was posed to me in a job interview.The question is from Estimate of Earthwork by Three Methods topic in section Road Estimating, Sanitary and Water Supply Work of Civil Engineering Drawing
Answer» The correct OPTION is (c) profile Easy explanation: The profile of a road consists of road slopes, called grades, connected by parabolic vertical curves. Vertical curves are used to provide a GRADUAL change from one road slope to another, so that VEHICLES MAY smoothly navigate grade changes as they travel. Sag vertical curves are those that have a tangent slope at the end of the curve that is higher than that of the beginning of the curve. When driving on a road, a sag curve would appear as a valley, with the vehicle first going downhill before reaching the bottom of the curve and CONTINUING uphill or level.

However, groundwater pollution may occur and can be a problem.
