For Students:

First, read Paragraphs A to D carefully to understand how neural growth and milestones are defined. Next, answer Questions 1 to 10 sequentially, paying close attention to words that alter precise meanings before checking your answers.

Cambridge Style Passage

Early Brain Growth and Developmental Milestones

4 Paragraphs (A–D)

A clean educational illustration of a toddler playing with wooden blocks, with subtle glowing lines representing brain c

The Center on the Developing Child at Harvard University says that more than 1 million new neural connections form every second in the first few years of life. It says that the first years are critical for building a healthy foundation. The early connections give either a strong or a weak base for the connections that form later.

The US Centers for Disease Control and Prevention, or CDC, says that skills such as a first step, a first smile and waving bye-bye are called developmental milestones. It says that milestones are things most children can do by a certain age, and that most means 75 percent or more of children. The CDC gives checklists for ages from 2 months to 5 years.

The CDC checklist for 15 months lists skills that most children have by that age. Most children take a few steps on their own. They also try to say one or two words besides "mama" or "dada", such as "ba" for ball or "da" for dog. The checklist is a guide, and each checklist covers one age.

I think the figures show why the early years matter, but I am not a doctor, and it seems that a checklist cannot say whether one particular child is developing well. I think the Harvard figure is a way to show how fast the brain grows, not a number that a parent can measure.

💡 How Language Connects Details in Academic Reading

Notice how writers present age-related facts smoothly by attaching descriptive time frames and specific examples:

"Children aged between two and five learn to talk at an amazing speed."

Why this works: The age comes right after the word children, so the sentence stays easy to follow.

Summary: The 15-Month CDC Checklist

The CDC checklist for 15 months outlines skills that most children achieve by that age group. For instance, most toddlers can take a few [9] on their own. Additionally, the passage emphasizes that any checklist should be interpreted as a general [10] rather than a tool to diagnose an individual child's health.
