Children typically start sitting and crawling around the age of 6-7 months. This is a developmental milestone that most babies reach during this time. At this age, babies have gained enough strength and coordination to sit up without support and begin to move around by crawling. It is important to note that every child develops at their own pace, so some may start sitting and crawling a little earlier or later than this average range.

The correct answer is "toddlers" because the given phrases "5 years old", "6 months", "infant", and "child" all refer to stages of development in a young person's life. "Toddler" is the term used to describe children who are between the ages of one and three, which fits within the context of the other phrases provided.

The correct answer is "3-5 years old". This age range is commonly associated with the developmental stage where children start to become more independent and creative. At this age, children have developed enough cognitive and motor skills to engage in imaginative play and create things on their own. They can use their imagination to build structures, draw pictures, or engage in other artistic activities. Therefore, "3-5 years old" is the most appropriate age range for children to start creating things.

The answer "3 years old" is the only option that matches the given list of time periods. The other options do not correspond to any of the mentioned time periods.

Permanent teeth typically begin to appear around 6 years old. This is when the first set of permanent molars usually erupt, followed by the lower central incisors. The eruption of permanent teeth continues throughout childhood and adolescence, with the last set of molars, known as the wisdom teeth, typically appearing between the ages of 17 and 21. The age of 6 is significant because it marks the transition from primary (baby) teeth to permanent teeth, which is an important milestone in dental development.

Children typically start babbling sounds around three months of age. This is an important developmental milestone in their language acquisition process. During this stage, infants experiment with different sounds by repeating consonant and vowel combinations. Babbling is a precursor to speech and helps children develop their oral motor skills and vocalizations. It is an essential step in their communication development before they start producing meaningful words and sentences.

The phrase "show off" typically refers to someone who tries to impress others by displaying their skills or possessions. In this context, the answer "4 years old" suggests that the person being referred to as a "show off" is 4 years old. This implies that at such a young age, they are already trying to draw attention to themselves or boast about their abilities or belongings.

At around four months old, children start recognizing smiles of recognition. This is because by this age, their visual perception and cognitive abilities have developed enough to distinguish and interpret facial expressions. They become more responsive to social cues and can differentiate between different emotions, including recognizing a smile as a sign of recognition or familiarity.

The given answer suggests that the individual in question is 4 years old. This age is typically when children start to develop social skills and are able to engage in group activities. At this age, they are more independent and capable of working collaboratively with others. The other options provided, such as 2 years old, 5 years old, 2 months, and 4 months, do not align with the ability to work in groups.

The given answer "3 - 5 years old" is the correct option because it falls within the age range commonly associated with the term "toddler." A toddler is typically defined as a child between the ages of 1 to 3 years old. Therefore, the age range of 3 to 5 years old aligns with the definition of a toddler and is the most appropriate choice among the options provided.

The given correct answer suggests that a person who enjoys collecting things is likely to be 6 years old. This age is commonly associated with children who start developing interests and hobbies, including collecting various items. At this age, children often show curiosity and a desire to gather and categorize objects that they find interesting.

The answer is 8 years old because "Mastering Reading" typically refers to the ability to read fluently and comprehend complex texts, which is a skill that is usually acquired around the age of 8. At this age, children have typically developed a strong foundation in phonics, vocabulary, and reading comprehension, allowing them to read independently and understand a wide range of texts.

Children typically start grasping objects around four months of age. At this stage, their hand-eye coordination and motor skills have developed enough to allow them to reach out and grab objects. While some children may start grasping objects as early as two or three months, it is more common for this milestone to be achieved around four months. By this age, infants are able to use their hands to explore and interact with their surroundings, which is an important step in their overall development.

The correct answer is 3-4 years old. This age range is most likely the appropriate age for children to engage in activities such as building block towers. At 3-4 years old, children have developed the necessary fine motor skills and hand-eye coordination to manipulate and stack blocks effectively. They are also at an age where they are curious and interested in exploring their environment through play, making block towers a suitable and engaging activity for them.

Object permanence is the understanding that objects continue to exist even when they are out of sight. At around 8 months old, infants begin to develop this cognitive ability. They start to realize that objects still exist even if they are hidden or moved. Prior to this stage, infants believe that objects cease to exist when they are no longer visible. Therefore, at 8 months, infants have reached a milestone in their cognitive development by understanding object permanence.

Babies typically start to understand words and simple commands between the ages of 8-10 months. At this stage, they may begin to recognize and respond to familiar words or phrases, such as their own name or common objects. They may also show signs of comprehension by following simple instructions or gestures. This is an important milestone in language development as it indicates that the baby is starting to understand the meaning of words and is laying the foundation for future language acquisition and communication skills.

The most likely explanation for the answer "6 years old" is that it refers to the age at which same-sex friendships start to become more common and significant in a child's life. At around 6 years old, children begin to develop more complex social skills and form deeper connections with their peers. This is also the age when they start attending school and interacting with a wider range of children. Prior to this age, friendships may still exist, but they are typically less stable and less focused on same-sex relationships.

The correct answer is 3 months. This suggests that infants are able to recognize familiar faces at a very young age, as early as 3 months old. This is supported by research which shows that babies have the ability to distinguish between familiar and unfamiliar faces at this age. The development of this ability is important for social interaction and bonding with caregivers.

This answer is based on the age milestones of a child. At 3 months old, a baby starts to develop more control over their body and may begin to lift their head and smile. At 12 months old, a child typically starts to walk and say a few words. The other options, 1 year old and 5 years old, are not accurate because they are equivalent to 12 months and 60 months respectively. 0 months is not a valid age as it represents a newborn baby.
