When approaching a roundabout, a driver must: A Stop completely behind the stop line B Wait for the traffic light to turn green
zvonat [6]

When approaching a roundabout, a driver must yield to traffic coming from the left.

<h3>The correct way to go around Roundabout</h3>
  • Always yield to oncoming vehicles in the circle as well as those crossing the street when you approach a roundabout crossroads. Before stepping inside, watch for a traffic pause.
  • When an emergency vehicle has a siren, air horn, red or blue flashing light, or all of these, one must surrender the right of way to it.
  • Similar to a regular multi-lane intersection, a multi-lane roundabout requires drivers to choose their lanes. Most of the time, the right lane is used to travel straight or make a right turn. Use the left lane if you want to drive straight or turn left.
  • The most crucial rule is that, unless there are specific road markings or signs that indicate otherwise, you must give way to traffic already on the roundabout when entering one.

hoa [83]

Answer:

D. Piaget

Explanation:

All the different options of this question refer to different psychologists who proposed different theories of development.

  • Erikson proposed a theory of social development in which the individual goes through different stages in the process of forming their personality and interacting with people.
  • Kohlberg proposed a theory of moral development in which the individual goes through different stages in their moral thinking and behavior.
  • Kohut proposed a theory of self as a way of understanding individuals from their own perspective and experiences.
  • Piaget proposed a theory of <u>cognitive development </u>in which infants and teenagers go through a series of stages and they develop a more formal and logic way of thinking in each one of them.

We can see that the theorist that actually is associated with a theory that has to do with cognitive development is Piaget. Therefore the correct answer is <u>D. Piaget. </u>

Which child is most likely to mention emotions such as pride, shame, embarrassment, and jealousy in conversation?
Harlamova29_29 [7]

8 year old Stacey.

At birth the infant has only the foremost elementary emotional life, but by 10 months infants display the total range of what are considered the fundamental emotions: joy, anger, sadness, disgust, surprise and fear.

As kids grow from grade-schoolers to preteens, you'll expect many changes from their physical appearances to their favorite activities. Children may experience feelings of embarrassment much earlier than scientists previously thought.

Infants begin showing a spontaneous "social smile" around age 2 to three months, and start to laugh pride spontaneously around age 4 months. In addition, between ages 2 and 6 months, infants express other feelings like anger, sadness, surprise, and fear.

Middle childhood (usually defined as ages 6 to 12) could be a time when children develop foundational skills for building healthy social relationships and learn roles pride that may prepare them for adolescence and adulthood.
