The answer to this question is firearm/handgun
The data indicate that the majority of murders happened during an attempt of robbery or when a fight breakouts between criminal groups
<span>On these occasions, the perpetrator will be most likely to be equipped with guns rather than any type of weapons because it provides the most destructive power with the cheapest price.</span>
<span>It can also be known as the enhanced entity model. This model, used in the creation of databases, allows for more precise creation of classes and groups. This allows the user to put together databases that are more specialized and group the objects together in more complex manners.</span>
I believe the answer is: <span>gender typing
During </span><span>gender typing, children would started to develop awareness on what gender they really are and started so seek information on how to act/behave from other poeple with similar gender characteristics. During this time, they would start to adopt </span><span>proper "masculine" and "feminine" behaviors that accepted by society.</span>
