An article in USA TODAY† describes a study of how young children learn. Sixty-four 18-month-old toddlers participated in the stu

dy. The toddlers were allowed to play in a lab equipped with toys, which also had a robot hidden behind a screen. The article states: "After allowing the infants play time, the team removed the screen and let the children see the robot. In some tests, an adult talked to the robot and played with it. In others the adult ignored the robot. After the adult left the room, the robot beeped and then turned its head to look at a toy to the side of the infant. In cases where the adult had played with the robot, the infant was four times more likely to follow the robot's gaze to the toy." Indicate whether the study is an observational study or an experiment. Give a brief explanation for your choice. (Hint: See Examples 1.2 and 1.3.) This is an observational study because the researchers observed how all the toddlers acted under the same conditions. This is an observational study because the researchers examined the toddlers observing adults and robots. This is an experiment because the researchers were using technological equipment, like robots. This is an experiment because the researchers assigned the toddlers to different experimental treatments.

Anvisha [2.4K]

Answer:

It is not always necessary to lie.

Explanation:

Lying is not "always" a necessity. Most times, people tell lies to get away from a situation: to deny allegations, to escape punishment or even to escape from shame of the moments. people that lie, if properly investigated, have something they are hiding or they usually have a bad situation (although not always) they want to get away from. This is why people lie. More so, some people also lie to cover their excesses or to gain advantage over a situation. This is the reason why when a person lies, he or she has broken the trust put in him or her by friends, family, colleagues and even bosses. So can we now say that, it is justifiable to break the heart of our loved ones because lie is a necessity? No! When a person is caught lying, trust goes out the window in most cases, and it has to be rebuilt again, all in the name of lie necessary.

From the situations stated above, it can therefore be concluded that, lying is not necessary if people are willing to face the consequence of  their actions or if they can stand the shame of their actions also.
